Disable go license generation as part of make tidy (#33747)

It seems something broken `google/go-licenses` (maybe related to go
1.24), and my findings are in
google/go-licenses#128 (comment).
I think it's best we disable this generation for now until a better
solution is found.

Also, enable showing stderr output so we can actually debug this thing.
For reference, these are the errors that currently apparently break the
tool:

```
E0228 05:15:27.005759   13158 library.go:117] Package text/tabwriter does not have module info. Non go modules projects are no longer supported. For feedback, refer to google/go-licenses#128.
E0228 05:15:27.005776   13158 library.go:117] Package net/http/fcgi does not have module info. Non go modules projects are no longer supported. For feedback, refer to google/go-licenses#128.
F0228 05:15:27.028122   13158 main.go:77] some errors occurred when loading direct and transitive dependency packages
```
