Fix outdated API names in Visual Studio grant-identity page

- PackageType.Main → PackageTypes.Main (correct enum name)
- package.Id.FamilyName → package.Id.FullName (RemovePackageAsync requires full name)
- Bump ms.date to 04/09/2026

Aligns VS variant page with corrected non-VS page. Addresses Copilot PR review feedback.
