2. What did you expect to see?
   tiup playground v8.5
   tiup playground 8.5
   tiup playground v8.5.0

When the version is specified like v8.5, 8.5.0, 8.5, it is resolved to v8.5.0 so that the corresponding package can be found.

3. What did you see instead?

Prometheus did not complete the version number, resulting in the package not being downloaded, but tidb/tikv/pd does.
