[bug#55701] [PATCH] gnu: Add go-github-com-google-go-jsonnet

[JOULAUD François]

This adds the jsonnet command. I would like to add too the jsonnet-fmt
command and the Python bindings but I struggle to understand how to do
it. I begin with the easy part using guix import.

I found that #:unpack-path and #:import-path are unintuitive, there is
room for better interface here, or at least some documentation.

* gnu/packages/golang.scm (go-github-com-google-go-jsonnet): New variable.
* gnu/packages/golang.scm (go-sigs-k8s-io-yaml): New variable.
