feat: support installing goreleaser v2

When the version we want to install is 2 or larger, the module is
namespaced in v2. This change allows us to keep installing v1 from
`github.com/goreleaser/goreleaser`, but for any other version, it will
append `/v$version` to the module path.

This should allow us to update goreleaser to v2 in
