Allow more db types for IPinfo mmdb files / reenable IPinfo in data adapter UI

[mpfz0r]

IPinfo recently changed the type field in their metadata.

old

mmdbctl metadata 24/asn.mmdb
- Binary Format 2.0
- Database Type ipinfo asn.mmdb

new

mmdbctl metadata newest/asn.mmdb
- Binary Format 2.0
- Database Type ipinfo generic_asn_mmdb_v4.mmdb

This is likely because they changed something in their release process, because the db type is just their import filename:

Relax our db type match to support this.
