Emergency Fix

When changing update_cp_org_libraries to allow for testing, I used the incorrect method when changing a list variable to a set. Which broke the function (adafruit/circuitpython-org Actions run):

  cd adabot
  python3 -u -m adabot.update_cp_org_libraries -o $GITHUB_WORKSPACE/bin/adabot/libraries.v2.json
Running circuitpython.org/libraries updater...

    contributors.add(get_contribs)
TypeError: unhashable type: 'list'
Error: Process completed with exit code 1.

This PR contains a fix for that.

Additionally, this break highlighted that the integration test did not catch this error; the mocked list_repos uses TestRepo which will not provide consistent contributor information. So, the test now includes a mocked result for contributor info.

Lastly, in running tests before pushing this PR, changes in adafruit/cookiecutter-adafruit-circuitpython#151 caused test failures. I updated the validator function with the new hardcoded link.

Thanks for the fix!
