Describe changes:

• ci: run CodeQL only on python changes

#12151 taking the approach of duplicating the file because it is easier to have the check in on section than using strategy.matrix.exclude where it looks complex to have the list of different files

Oh CodeQL says

Warning: Code scanning cannot determine the alerts introduced by this pull request, because 1 configuration present on refs/heads/master was not found: .github/workflows/codeql.yml:analyze/language:python

So, CodeQL says we analyzed python in master and we did not analyze it in this PR, so this may be dangerous

I think it is fine
