Correct three readme facts that were wrong

Found by following my own instructions and having them fail.

- Deploys run from /root/devops/hostinger, a clone of this repo, not from
  /opt/t4t-gateway, which does not exist on the host. `git pull` is the
  deploy step; the readme was telling people to rsync into a path that
  isn't used, which is how the stamp-monitor service ended up edited on
  the host and missing from this repo for a day.
- `internal` is not an attachable overlay, so `docker run --network
  internal ...` is refused outright. Query Bee through a container that
  is already on the network instead.
- The monitor listens on 3000, not 8088.
