[FEAT]: Add pre-commit cache to _reusable-test-code.yml

[nfelt14]

Description

It could be nice to have a pre-commit cache so that pre-commit can run faster as a part of any test-code.yml workflows.

Additional Information

It could be as simple as adding this step before running tox:

- uses: actions/cache@v4
  with:
    path: ~/.cache/pre-commit
    key: pre-commit|${{ env.pythonLocation }}|${{ hashFiles('.pre-commit-config.yaml') }}
