Support Semantic Versioning 2.0.0

[Thilas]

Description Of Changes

This PR brings SemVer 2 support to AU.

I also change a bit the parsing behavior to match chocolatey normalization of versions:

• 1.2 => 1.2.0
• 1.2.3.0 => 1.2.3

Last thing, I try to "improve" versions so that a SemVer 1 prerelease becomes SemVer 2

• 1.2.3-rc4 => 1.2.3-rc.4

Motivation and Context

This change comes from chocolatey now supporting SemVer 2.
