New scan workflow + sonar project config file to enable sonarqube scans

[dandelany]

Per MGSS/AMMOS requirements, we need to use a combination of CodeQL + SonarQube for security scans moving forward, via GH actions. This will ultimately be implemented in all PlanDev repos & will replace the existing CodeQL scans.

This is affected by this nasa-scrub issue and contains a temporary workaround to avoid it, which we can easily remove later when fixed upstream.

What Enabling Code Scanning Means:

• The 'Security' tab will display more code scanning analysis results (e.g., for the default branch).
• Depending on your configuration and choice of analysis tool, future pull requests will be annotated with code scanning analysis results.
• You will be able to see the analysis results for the pull request's branch on this overview once the scans have completed and the checks have passed.
