CI/CD | Run `backUp()` Unit Tests

[ReedClanton]

Description

Update GitHub actions so unit tests of backUp() are run. If any fail, merging is blocked.

High Level Solution Description

Add a GitHub action yml file for each set of tests that cover given CUT that runs all relevant unit tests.

Alternative Solution(s)

At this point, I don't know much about GitHub actions, so it may be better to structure the yml files differently so it's more performant.

• Create Basic Set of Unit Tests of createHeaderFooter #13
• Make backUp() not Bad... #22
• Get shellspec Unit Tests Running on GitHub Runner #24
• Create Unit Tests of backUp() and Any Util Code #39

Additional Context

This should be trivial once #24 is done.
