ci: run framework tests if frameworks.yml modified [backport 2.0] (#7381)

Backport 7894f6e from #7379 to 2.0.

Currently if you just edit only test_frameworks.yml, we won't actually
run those tests, which keeps PRs that do this from being merged since
the tests don't run e.g.:
#7374
With this change we check if this file is changed, if so, we make sure
to run them.
