refactor(lexicon): remove vote XRPC procedure definitions
Remove createVote and deleteVote XRPC procedure lexicons. These
endpoints are no longer exposed by the AppView.
Clients use standard atProto repo operations instead:
- com.atproto.repo.createRecord
- com.atproto.repo.deleteRecord
Keep social.coves.interaction.vote.json (record type definition)
as it's still needed for Jetstream indexing.
Deleted:
- social.coves.interaction.createVote.json (67 lines)
- social.coves.interaction.deleteVote.json (37 lines)
