Update Python actions to v5

[reactive-firewall]

Issue is that actions/setup-python@v4 is in use when actions-setup-python@v5 (circa v5.1.1) is available to use.

See also Issue #40 for related flaw in test.

Additional Information:

Unlike the suggestion from the naive actions/scorecard recommendation of using only the hash, the tag v5 is code-signed (see https://github.com/actions/setup-python/releases/tag/v5.0.0 and https://github.com/actions/setup-python/releases/tag/v5.1.1 for more) and acceptable for use with this project instead of the less maintainable hash (as git treats the hash and tag ref with the same indifference when resolving them to a matching git blob).
