Generate go-licenses during tidy again (#21108)

We can not have the `frontend` target depend on golang because of they
way drone is set up. Move the `go-licenses` generation back into `tidy`
where it will now also be checked for consistency during `tidy-check`.

(I assume all `main` branch builds should currently fail [like
this](https://drone.gitea.io/go-gitea/gitea/60244/1/11)).

The reasony why it shouldn't be treated the same as for example `go
generate` is because output files are checked in. tidy is imho the
optimal target to run this after.
