did:tdw driver + example no longer works

[ankurdotb]

Possibly due to the upstream method name change to did:webvh, the specified example for did:tdw throws an error:

[internalError] Driver cannot retrieve result for did:tdw:QmbnQXj7DhWFrmgjDPKZCybn8fkKW7Wze57SQHpwsSQ7NZ:gist.githubusercontent.com:brianorwhatever:9c4633d18eb644f7a47f93a802691626:raw: 400 Bad Request ('did:webvh:0.5' protocol unknown.)

Tagging @brianorwhatever on this as it seems the Docker image is published under your Dockerhub repository. (I assume the driver code is in a DIF repo, so if there's no DIF Dockerhub account it might be possible to published under DIF to Github Container Registry instead, if we want to avoid publishing under a personal Dockerhub but I leave that suggestion up to the DID method's authors.)
