Remove axios in favour of native in API docs (#7312)

Massive thanks to @thomasheartman for digging around GitHub and figuring
out how to do this.

Regrettably it doesn't use the native fetch, which is what I thought it
would do. It's more code so I'm happy to close it but I still think it's
worth the discussion
