ARCH-2011 - Adding tests

[danielle-casella-adams]

Summary of PR changes

• Adding Tests
• Small tweak to the action source code to update description & string check
• Small tweak to action.yml so it's more obvious what is different between the two builds

PR Requirements

• For major, minor, or breaking changes, at least one of the commit messages contains the appropriate +semver: keywords.
  • See the Incrementing the Version section of the repository's README.md for more details.
• The action code does not contain sensitive information.

NOTE: If the repo's workflow could not automatically update the README.md, it should be updated manually with the next version. For javascript actions, if the repo's workflow could not automatically recompile the action it should also be updated manually as part of the PR.
