Remove "prerelease: true" from WinGet Configuration

[denelon]

Description of the new feature / enhancement

The Microsoft.WinGet.DSC module is GA. There may be conflicts introduced with preview versions of the module.

The "prerelease: true" directive should be removed to avoid problems.

Note

I'll make a PR shortly

Scenario when this would be used?

When a developer uses the WinGet Configuration File to setup their development environment it should be using stable modules if they are available. Other modules may still be in preview, so those should still have the directive for prerelease.
