JIT workflow is executed on unrelated changes in my local fork

[sobolevn]

Bug report

There are several potential problems in this:

1. We have a failing JIT test job, CC @brandtbucher, link: https://github.com/sobolevn/cpython/actions/runs/7722621656/job/21051101804 Note, that it does not fail in 100% of cases, only sometimes
2. It is executed in my fork, while no other tests are
3. It is executed on a doc-only change, while other tests ignore such changes

I will send a PR to fix 2. and 3.
