What was changed

Expose Versioning Info from Describe Task Queue.
Looks like this:

 % ./temporal task-queue describe --legacy-mode -t hello_world --task-queue-type-legacy workflow  -n worker-controller-demo.a2dd6 --api-key=$APIKEY --address=us-east-1.aws.api.temporal.io:7233
Pollers:
  Identity  LastAccessTime  RatePerSecond

Versioning Info:                                                                                                                                                                               
  CurrentVersionDeploymentName  helloworld-demo/staging
  CurrentVersionBuildID         v0-3-0-good-patch-5db8
  RampingVersionDeploymentName  helloworld/staging
  RampingVersionBuildID         v0-3-0-5f57
  RampingVersionPercentage      1
  UpdateTime                    5 months ago

Why?

So people can see the current and ramping version of a task queue from the task queue's perspective.
