do not require new itkclustererror folder tag for each major geotag version

Jiri Masik requested to merge jmasik/athena:itkclustererror-folder-tag into 23.0

The current code requires a new tag version with each new major version of the geotag - specify a tag by the flags instead.

Related to deployment of a new geotag in ATLSWUPGR-188 and ATLIDTRKCP-456.

FYI @tstreble and @pagessin

I'll make a request to link the tag to a future global tag separately
