To avoid everyone needing to take a dep on `rules_go`, we
do the following:

1. Regular Bazel users need to load `bazel_skylib_gazelle_plugin_workspace`
   and call that, and then `bazel_skylib_gazelle_plugin_setup`

2. `bzlmod` users need do nothing, but we now include the
   `rules_go` dep in the `MODULE.bazel` shipped in the release.
    This is fine, because `bzlmod` will lazily load
    dependencies.

… match the ones in gazelle

…//... works as expected
