Refactor repo structure into separate repositories

[0xjjpa]

• [x] Refactor our folders into their respective repository
  • [x] Move chat into https://github.com/hoprnet/hopr-chat.
  • [x] Move server into https://github.com/hoprnet/hopr-server.
  • [x] Move protos into https://github.com/hoprnet/hopr-protos.
• [x] Fix the .github/workflows pipelines to ensure they work in their new repos.
  • [x] node.yaml should run the project's test suite on PR.
  • [x] publish.yaml should do the following on tag push
  • [x] create a binary and docker image for chat
  • [ ] create a docker image for server
  • [x] publish an npm package for protos

The best way to ensure this is properly working,

• [ ] Create a PR with a new feature e.g. feature/increase-version
• [ ] Add the label minor patch and merge when passing, this will run the node.yaml action
• [ ] On merge RangerBot will create a tag that will trigger the publish.yaml action.
