Pull request overview

Updates the Azure DevOps publish pipeline to make module versioning more flexible during publishing, including support for prerelease publishing via a new pipeline parameter.

Changes:

• Adds a new prerelease pipeline parameter for publishing prerelease/alpha suffixes.
• Reworks the PowerShell manifest-editing step to update ModuleVersion via regex rather than a fixed literal replacement.
• Updates the manifest-editing logic to set/clear the Prerelease field based on the new parameter.
