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:

There are segfault issue for finite-shot hermitians tests with Catalyst on arm64-macos. It looks like closing libscipy_openblas.dylib has a side effect that leads to the segfault and using RTLD_NODELETE mitigates that.

There are segfault issue for shor algorithm tests with Catalyst on arm64-macos. It looks like closing libscipy_openblas.dylib has a side effect that leads to the segfault and using RTLD_NODELETE mitigates that.

I think the current issue only appears when running finite-shot hermitians, so not necessarily related to the original problem found with Shor.

Thanks @dime10 for the updates! Just updated the description.

Thanks! Not sure how you guys handle it but I often leave comments in the code for why a tweak like this was necessary to help future developers.
