fix: remove references to x, correct community

* Remove references to x.com since that's not actively being used for
  news posts
* Add reference to mastodon on get in touch since that is being used
* Clarify that community chats are on both Discord and Matrix
* Clarify that the community chat bridge isn't guaranteed, and that
  Discord has more activity
