CI-CD Updates (#768)

Browse source 
* 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
