Update & Reorganize setup instructions

[devyntk]

Since Dozer now requires intents, show how to do that in the setup instructions (the bot doesn't boot if they're not enabled). The developer portal has also gotten a makeover since those screenshots were taken, so new screenshots would be nice. In addition, we need to add instructions on how to add Reddit & Twitch API keys, and I think it's a good idea to separate out all the non-essential API keys to a separate section.

I've taken out a few things that may be confusing in the instruction-rewrite branch

Whoever takes this on should also document the use of the docker-compose setup. It's quite simple, but should be documented.

Checklist:

• Intents (See changed readme and gitignore a bit #314 )
• Update screenshots of Discord API token generation
• Document use of Docker-Compose
• Create a separate markdown file with instructions on nonessential keys:
  • Google Maps API
  • Reddit
  • Twitch
  • The Blue Alliance
  • The Orange Alliance
• Document instructions for configuring Dozer in a server. This should be done in RST format in the docs folder so that Sphinx can parse the data for webpage generation.

Everything on that checklist should be selected except for the token instructions for Reddit, Twitch, and The Orange Alliance; as well as that that last item.
