Bumping PTB & Refactoring

[Bibo-Joshi]

General Todo list with things that can be done when/if I get back to it.

• Use BotCommandScopes for admin commands
• Use arbitrary callback data instead of all those patterns
• Use a custom class for bot_data to avoid all those key constants
• Use pyupgrade & maybe isort in the pre-commit settings
• Maybe use stuff like sphinx-paramlinks and the nitpicky settings for the docs
• update AkaDressen parsing by leveraging akadressen-utils
