Publishing Test Reports to GitHub Pages

[natescherer]

Just wanted to leave a note that I've successfully developed a method to publish test results to GitHub Pages, but I've built it on top of the work I already did for #22 so I can't directly submit a PR until that PR is accepted, since #22 changes how inputs and outputs work.

If you're curious to see, you can see the output here: https://natescherer.github.io/ChangelogManagement/testreports/

And the code is in this branch: https://github.com/natescherer/pester-tests-report/tree/feature/pages-publishing
