CI-CD Updates (#768)
* Use new version of CI-CD Actions * Use cSpell spell check, and use ubuntu-20.04 for formatting check * Format and spell check all files in the portable directory * Remove the https:// from #errors and #warnings as uncrustify attempts to change it to /* * Use checkout@v3 instead of checkout@v2 on all jobs ---------
