Moving all the config files into a single config directory

[Linus045]

As discussed here: https://github.com/CyberPunkMetalHead/gateio-crypto-trading-bot-binance-announcements-new-coins/pull/119#r775889308_

The config files (config.yaml and auth.yaml) should get moved into their own directory to keep it more organized.

To implement that change. all paths need to be updated (maybe utilize constants to make this easier in the future). The Dockerfile is also affected, so make sure the Docker builds/runs correctly afterwards.
