To help catch issues from PRs that would regress behavior,
adding a GitHub action similar to unit tests to run integration
tests.
GitHub actions do not pass secrets to actions which are triggered
by PRs sent from forks. As a result, it is not possible to have CI
run on the forks from external contributors. Currently implementing a
process that requires manual review until a more direct solution is
found.
Adding some basic instructions for future maintainers and contributors.
