Add Misskey

Name: Misskey
Homepage: https://misskey-hub.net/en/
Short description: A federated social media platform
Optional API documentation URL: https://misskey-hub.net/en/docs/api

Easier than API could be the same scraping method used on other similar platforms, where the fingerprint is in the bio.

Since Misskey is ActivityPub-compatible, hopefully this one will just work when we get the unified ActivityPub claim verification [1] working.

Since universal activitypub verification got shipped I'm marking this as resolved! 🚀

To verify your Misskey account simply use the generic activitypub service provider: https://docs.keyoxide.org/service-providers/activitypub/
