Run test suite with GitHub Actions

[charlestian23]

Description

The test suite now runs with GitHub Actions for any pull request or commit into master or dev. The test suite is run on Ubuntu, macOS, and Windows.

As far as I can tell, this should work, since I added some dummy tests (which I have deleted now), and those tests were marked as failed. I have not tested by purposely breaking a rule and then seeing if the corresponding test breaks since our test suite is under construction currently and I'm not sure which tests are completely reliable and which are not.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Enhancement (improvement to an already existing feature)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
