feat: add Tor support for relay service

Add Tor support for the relay service in the docker-compose file. Also, rename the service from `wot-relay` to `relay`. Add a new `torrc` configuration file and a `.gitignore` file in the `tor/data` directory to prevent sensitive data from being tracked. Also, create a new `docker-compose.tor.yml` file for Tor-specific configurations.
