Description

Can you tell I'm trying to finish Astro's rewrite?

Anyways, yeah, channel_types wasn't being checked for syncing, so this fixes that.

Changes

• Add an entry for channel_types for the options_lookup in _compare_options.

Test Scenario(s)

• Make a slash command with a channel option type and with a specified channel_type.
• Sync it, change the channel type, then sync again.
• Commands are still the same, the logger shows that no commands were overriden.
