MAINT: Implement a validation method for the `OrthologFileFmt`

[Sann5]

Improvement Description
Implement a validation method for the OrthologFileFmt format (defined in the genome_data module). This format defines a FileCollection in the SeedOrthologDirFmt format which is associated with the SampleData[BLAST6] semantic type. This semantic type is used in the eggnog-diamond-search action from q2-moshpit.

Current Behavior
No validation method implemented, i.e. no validation is taking place.

Proposed Behavior
Validate these files which have a well-defined format (BLAST6).

Hey @Sann5! We'd be happy to get this into the 2024.10 release - is this something that your team is planning on working on, or would you like us to implement?

Hey @lizgehret. It would be great if you could implement this 👍🏼. We were not planning on doing it anytime soon.
