Edu 2073 Remove Realtime API faqs

[franrob-projects]

This PR integrates the Realtime API FAQs into the docs:

• ably-js page unload behaviour

• Why is my Ably realtime connection sometimes disconnecting and reconnecting?

• Will I receive an error if a client publishes with the connection in the Failed, Disconnected or Suspended states?

• How can I use ably-js session recovery over a page reload when I have multiple SDK instances for the same origin?

• SSL certificate issues communicating with Ably

• Is it necessary to implement auto-renewal of tokens when using Token Auth?

• Is it possible to dynamically change the channels a user has access to without disconnecting?

• Do you have a max TTL for tokens?

• Tidy up commit
