bioportal client should implement mapping between OBO prefixes and bioportal prefixes

Currently using the bioportal client with some ontologies like FBbt, WBbt results in failure, because bioportal uses different names eg FB-BT

We should implement the mapping - using bioregistry? in this lib or in https://github.com/cthoyt/ontoportal-client?

Start by tracing the bioportal client entry point and reproducing the FBbt or WBbt failure. Compare the OBO and BioPortal prefixes, then review bioregistry and ontoportal-client to determine where the mapping belongs. Done means these ontology lookups work without breaking existing client behavior.
