update to go1.21.4
go1.21.4 (released 2023-11-07) includes security fixes to the path/filepath
package, as well as bug fixes to the linker, the runtime, the compiler, and
the go/types, net/http, and runtime/cgo packages. See the Go 1.21.4 milestone
on our issue tracker for details:

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.
