Preview versions in `index.json` is not valid semantic versions

[o-l-a-v]

Describe the bug

Preview version numbers in index.json, fetched with az extension list-available, is not valid semantic versions.

Example:

PS > az extension list-available | ConvertFrom-Json | Select-Object -Last 1

experimental : False
installed    : False
name         : workloads
preview      : True
summary      : Microsoft Azure Command-Line Tools Workloads Extension.
version      : 1.1.0b2

PS >

If one ads a hyphen to it 1.1.0b2 => 1.1.0-b2, it becomes valid.

Why use a non-standard version scheme? Makes it harder to parse.

Thank you for opening this issue, we will look into it.

So Python has its own version scheme?

• https://peps.python.org/pep-0440/#version-scheme

Dotnet has NuGet.Versioning which also isn't semver compatible, so maybe I can't complain.

Would still be great with a semver compatible version number in the metadata somewhere.
