Initial work on Annotater

[modmuss50]

This PR contains the initial work for a new Javadoc API that will allow developers to contribute javadoc for the Minecraft jar in a "wiki" like manner.

• OAuth based authentication with GitHub (Discord to come later)
• JWT authentication using Refresh Tokens
  • The server does not store any user data currently (likely to change soon)
• A an example API to query and edit Javadoc in Minecraft classes, to be replaced by @Player3324 side of things.

I have been working on the web UI side of this as part of https://mcsrc.dev/ I think we will likely host a variation of mcsrc.dev that has the javadoc editing stuff enabled.

TODO:

• Roles (trusted/admins)
  • Read from github team?
• Discord auth
• Everything else 😅
