Run `go generate` and `go vet` on all packages (#30529)

Fixes: https://github.com/go-gitea/gitea/issues/30512

I think this does mean those tools would run on a potential `vendor`
directory, but I'm not sure we really support vendoring of dependencies
anymore.

`release` has a `vendor` prerequisite so likely the source tarballs
contain vendor files?
