Replace solrizer reference so that feature works with hyrax 3+

Addresses:
#699

This change might not work with hyrax < 2.8, since it looks like solrizer got merged into activefedora in 12.0.0, so if we need to support those versions of hyrax we will likely need to add some logic in here to decide whether to use solrizer or activefedora.

I also suspect this code might not be getting fully tested, since bulkrax is using hyrax 3, but no tests seem to be impacted by this issue.

I don't understand what the "PR has required labels" rule requires me to change?

Also wanted to make sure we are okay with the hyrax version requirement going up, as discussed above

Bulkrax has the following requirement:

Error: Label check failed: required 1 of patch-ver, minor-ver, major-ver, ignore-for-release, but found 0.

I've updated this PR to make it backwards compatible with older versions of hyrax. Could someone trigger the workflows again?
