Add a new go pipeline to only manage deps

Melange Pull Request Template

This PR creates a separate go pipeline to manage golang dependencies keeping the current go/build compatible with the initial logic. With this new go pipeline, we can now separate the treatment of go dependencies from the go build commands that many times is handled in a different way depending of the project, e.g. using make targets.

Functional Changes

• This change can build all of Wolfi without errors (describe results in notes)

Notes:

SCA Changes

• Examining several representative APKs show no regression / the desired effect (details in notes)

Notes:

Linter

• The new check is clean across Wolfi
• The new check is opt-in or a warning

Notes:

I feel we could extend this pipeline to support go mod edit calls in the future.
