Updates and corrections

[AbstractUmbra]

Description

Updates some key features of the bot to reflect new goings on in the server and sister servers.

• Clean up around dependencies

  • requirements files were outdated and unmaintained, so they have been removed
  • specify the speed extra of discord.py
  • update all dependencies to date

• Webserver config entry

  • conditionally spawns the StarlettePlus app if the required config keys are present, and also allows setting the host and port arguments. Expansible to included others if needed.

• Docker

  • fix warning on ENTRYPOINT directive for non-JSON based usage. (python run -O ... vs ["python", "run", "-O", "..."]).
  • re-order some keys in docker compose for sanity
  • remove deprecated version key in compose
