`az version` of Edge builds should give a version number different to releases

**Related command**
`az version`

**Is your feature request related to a problem? Please describe.**
I currently see no possibility to find out whether I am using the normal az release or the Edge build from the command line. This makes it harder to analyze problems, which may or may not depend on whether it is an Edge build.

**Describe the solution you'd like**
When running `az version`, it should print a special version number for non-releases. For example, it might say 2.45.0-edge or 2.45.0.377 (where 377 is some kind of commit or build counter).

**Describe alternatives you've considered**
In Windows, I can look into "Programs and Features" how many Azure CLI installations exist. If it is more than one, chances are that one is the edge build. Other than that, I can only deduce it from behavior that I know is different in the Edge build.
