feat(github): add github integration

[ReenigneArcher]

Description

This PR aims to more tightly integrate GitHub with our discord bot.

Main features to add

1. Assign roles based on GitHub sponsorship status
2. Assign dev-user role based on GitHub account... (whether it exists, has contributed, or something along those lines)

TODO:

• Persist OAuth status?
• Periodically check GitHub user's for sponsor status, and add user to sponsor roles, or revoke accordingly
• Callback to public URL
• Possible to hide disocrd bot IP?
• Improved SSL certs
• Update dockerfile
• Update readme/docs
• Add/update unit tests
  • Unit tests hang on unix due to async nonsense
  • Unit tests do not post comment even though tests pass (on Windows)
