Change the format of release names on GitHub.
Change the format of release names on GitHub.

For example:

Old style: "3.0.0-beta01 release of Google.Cloud.Dialogflow.V2"
New style: "Google.Cloud.Dialogflow.V2 version 3.0.0-beta01"

Benefits:

- Consistent with the commit style and elsewhere that we refer to releases
- Effectively "most significant part first" making it easier to scan

Drawbacks:

- Inconsistency with history, unless we decide to automatically
  reformat all old releases (which is feasible...)
