DataQualityConfigurations: use GIT hash from release metadata

Frank Winklmeierrequested to merge
fwinkl/athena:dqi into 23.0

Instead of embedding the git hash into the cmake commands, which triggers a re-build for each CI run, use the release metadata. If we ever start building the AthDataQuality project again, we need to include the PyUtils package.

Also apply some other minor code fixes.

Closes ATLINFR-4893.
