Rename or alias the "PrereleaseLabel" property to match the display column "Prerelease"

[Jaykul]

Summary of the new feature / enhancement

It's confusing to Find-PSResource PowerShellGet -Prerelease -Version * and see the Prerelease column, and then try to | Format-Table Name, Version, Prerelease, Tags and find there's no content in that third column...

Proposed technical implementation details (optional)

Please add an AliasProperty or rename the original property
