[release-branch.go1.22] cmd/go/internal/modfetch: do not trust server to send all tags in shallow fetch
Newer git versions (at least git 2.47.1) do not send all the matching tags
for a shallow fetch of a specific hash anymore. The go command assumes
that git servers do this. Since that assumption is broken, use the local
copy of the remote refs list to augment the tags sent by the server.
This makes the cmd/go/internal/modfetch tests pass again with newer git.
For #71261
Fixes #71262
