Add conditional logic to allow CI and Make

[MichaelThamm]

TODO

• Undo the removal of the if conditional in the charm-quality-checks.
• Switch branches back to main before merging
• Test Makefile in Mimir repo
• Test Tox in Loki repo
• Cleanup draft PRs and branches

Test the following cases:

• Tox with static
• Make without Scenario
• Make with test failure

Fixes #249

This conditional logic ensures that we do not run Make if the test has failures. This also assumes that the whole test suite is ran for each repo even if there are no (e.g. scenario) tests which exist.

This would require repos that have Make, have each test type with a valid recipe. For example, if a repo does not have Scenario tests, the Make recipe would be:

scenario:
	echo "no scenario tests for this repo"

Check if the Make recipe exists before executing
