vendor: migrate to github.com/go-viper/mapstructure/v2 v2.0.0

github.com/mitchellh/mapstructure will no longer be maintained by the author,
and github.com/go-viper/mapstructure is nominated as the endorsed fork.

- v1.x changes since last release from mitchellh: https://github.com/go-viper/mapstructure/compare/v1.5.0...v1.6.0
- v2.0 changes: https://github.com/go-viper/mapstructure/compare/v1.6.0...v2.0.0

Breaking changes

Error is removed in favor of errors.Join (backported from Go 1.20 to preserve
compatibility with earlier versions)

What's Changed

- feat!: update module path
- build: update dev env
- feature: add StringToBasicTypeHookFunc and support complex
- Add an example showing how to use a DecodeHookFunc to parse a custom field.
- Remove exposed error type
- Replace internal joined error with errors.Join

+![Go Version](https://img.shields.io/badge/go%20version-%3E=1.18-61CFDD.svg?style=flat-square)
+
+mapstructure is a Go library for decoding generic map values to structures
+and vice versa, while providing helpful error handling.
+
+This library is most useful when decoding values from some data stream (JSON,
+Gob, etc.) where you don't _quite_ know the structure of the underlying data
+until you read a part of it. You can therefore read a `map[string]interface{}`
+and use this library to decode it into the proper underlying native Go
+structure.
+
+## Installation
+
+```shell
+go get github.com/go-viper/mapstructure/v2
+```
+
+## Migrating from `github.com/mitchellh/mapstructure`
+
+[@mitchehllh](https://github.com/mitchellh) announced his intent to archive some of his unmaintained projects (see [here](https://gist.github.com/mitchellh/90029601268e59a29e64e55bab1c5bdc) and [here](https://github.com/mitchellh/mapstructure/issues/349)). This is a repository achieved the "blessed fork" status.
+
+You can migrate to this package by changing your import paths in your Go files to `github.com/go-viper/mapstructure/v2`.
+The API is the same, so you don't need to change anything else.
+
+Here is a script that can help you with the migration:
+
+```shell
+sed -i 's/github.com\/mitchellh\/mapstructure/github.com\/go-viper\/mapstructure\/v2/g' $(find . -type f -name '*.go')
+```
+
+If you need more time to migrate your code, that is absolutely fine.
+
+Some of the latest fixes are backported to the v1 release branch of this package, so you can use the Go modules `replace` feature until you are ready to migrate:
+
+```shell
+replace github.com/mitchellh/mapstructure => github.com/go-viper/mapstructure v1.6.0
+```
+
+## Usage & Example
+
+For usage and examples see the [documentation](https://pkg.go.dev/mod/github.com/go-viper/mapstructure/v2).
+
+The `Decode` function has examples associated with it there.
+
+## But Why?!
+
+Go offers fantastic standard libraries for decoding formats such as JSON.
+The standard method is to have a struct pre-created, and populate that struct
+from the bytes of the encoded format. This is great, but the problem is if
+you have configuration or an encoding that changes slightly depending on
+specific fields. For example, consider this JSON:
+
+```json
+{
+  "type": "person",
+  "name": "Mitchell"
+}
+```
+
+Perhaps we can't populate a specific structure without first reading
+the "type" field from the JSON. We could always do two passes over the
+decoding of the JSON (reading the "type" first, and the rest later).
+However, it is much simpler to just decode this into a `map[string]interface{}`
+structure, read the "type" key, then use something like this library
+to decode it into the proper structure.
+
+## Credits
+
+Mapstructure was originally created by [@mitchellh](https://github.com/mitchellh).
+This is a maintained fork of the original library.

-# mapstructure [![Godoc](https://godoc.org/github.com/mitchellh/mapstructure?status.svg)](https://godoc.org/github.com/mitchellh/mapstructure)
-
-mapstructure is a Go library for decoding generic map values to structures
-and vice versa, while providing helpful error handling.
-
-This library is most useful when decoding values from some data stream (JSON,
-Gob, etc.) where you don't _quite_ know the structure of the underlying data
-until you read a part of it. You can therefore read a `map[string]interface{}`
-and use this library to decode it into the proper underlying native Go
-structure.
-
-## Installation
-
-Standard `go get`:
-
-```
-$ go get github.com/mitchellh/mapstructure
-```
-
-## Usage & Example
-
-For usage and examples see the [Godoc](http://godoc.org/github.com/mitchellh/mapstructure).
-
-The `Decode` function has examples associated with it there.
-
-## But Why?!
-
-Go offers fantastic standard libraries for decoding formats such as JSON.
-The standard method is to have a struct pre-created, and populate that struct
-from the bytes of the encoded format. This is great, but the problem is if
-you have configuration or an encoding that changes slightly depending on
-specific fields. For example, consider this JSON:
-
-```json
-{
-  "type": "person",
-  "name": "Mitchell"
-}
-```
-
-Perhaps we can't populate a specific structure without first reading
-the "type" field from the JSON. We could always do two passes over the
-decoding of the JSON (reading the "type" first, and the rest later).
-However, it is much simpler to just decode this into a `map[string]interface{}`
-structure, read the "type" key, then use something like this library
-to decode it into the proper structure.
