[rmarinho]

Description of Change

This pull request introduces several changes to the versioning system for our handler, leveraging the .NET Arcade versioning rules. The changes include moving the arcade to the 8.0 channel and updating xharness. This update ensures that our versioning scheme aligns with the established rules and practices, enhancing consistency and predictability in our build process.

Key Changes

• Move the arcade to the 8.0 channel.
• Apply Arcade versioning rules.
• Update xharness to align with the new versioning system.

Versioning Scheme

Taking the following example:

• Major: 8
• Minor: 0
• Patch: 40

The PatchNumberDate is calculated based on the format "yyyymmdd.Rev", producing something like 24264.1.

• Local builds: 8.0.40-dev.{PatchNumberDate}
• PR and CI builds: 8.0.40-ci.{PatchNumberDate}

Branching Strategy

1. Servicing Branches:

   • When creating a servicing branch from the main branch, update the PreReleaseVersionLabel to servicing and set StabilizePackageVersion to true.
   • Example: Release servicing - 8.0.40

2. Preview Branches:

   • When creating a preview branch from the net9 branch, update the PreReleaseVersionLabel to preview , the PreReleaseInteractionVersion to the number of you want and set StabilizePackageVersion to true.
   • Example: Release previews - 8.0.40-preview.1.{PatchNumberDate}

Implementation Examples

• Local Build: 8.0.40-dev.24264.1
• PR and CI Build: 8.0.40-ci.24264.1
• Servicing Release: 8.0.40
• Preview Release: 9.0.0-preview.1.24264.1
