Before submitting

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 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:
Currently Arm GPU CI runners may be reused between runs, and there is no cleanup job after each runs. This means that caches/wheels from previous runs contaminate later runs.

Description of the Change:
Clean cache after each Arm GPU CI runs. E.g. here

Benefits:
No contamination between runs.

Possible Drawbacks:

The failures here for ARM CUDA LTensor are fixed in the other PR - I didn't want to combine the two since that one was already approved, so I don't want to contaminate that

In this case, please change the aimed branch to the other PR branch. This way we can see the combined effect.
