Docker Desktop currently ships with the "cloud integration" wrapper,
which outputs an additional ContextType field in the JSON output.
While this field is non-standard, it made its way into Visual Studio's
Docker integration, which uses this to exclude "aci" and "eci" context
types that are not supported by Visual Studio.
This patch;
- conditionally adds a ContextType field to the JSON output
- but ONLY when using the default "{{json .}}" or "json" formats
(which are the formats used by Visual Studio)
- if the context is a "aci" or "eci" context, that type is
preserved, otherwise the default "moby" type is used.
