Build LK with GCC 11 for testing CIs (#1013)

Please complete the following checklist when submitting a PR:

- [ ] All new features must include a unit test.
If you've fixed a bug or added code that should be tested, add a test to
the
      [`tests`](../tests) directory!

- [ ] All new functions and code must be clearly commented and
documented.
If you do make documentation changes, make sure that the docs build and
      render correctly by running `make docs`.

- [ ] Ensure that the test suite passes, by running `make test`.

- [ ] Add a new entry to the `.github/CHANGELOG.md` file, summarizing
the
      change, and including a link back to the PR.

- [ ] Ensure that code is properly formatted by running `make format`.

When all the above are checked, delete everything above the dashed
line and fill in the pull request template.

**Context:**

PR #1007 forced all CIs to build and test Kokkos and Lightning-Kokkos
with GCC-13. [This change broke the LK testing
action](https://github.com/PennyLaneAI/pennylane-lightning/actions/runs/12075970714/job/33676642868)
as we still use GCC11 for testing Lightning, and GCC13 for building
wheels inside manylinux_2_28. This PR reverts that change for now :(
