Add Applebot definition (#589)

* Add Applebot definition

Adds Apple's search indexing bot, and allowlists it by default.

Allowlisted by default because it is equivalent to Googlebot/Bingbot. Remove Applebot from `ai-robots-txt.yaml` for the same reasons.

Remove `Applebot-Extended` from `ai-robots-txt.yaml` as it has no effect.

* chore: spelling
