Make WinGet config files consistent with new recommendations

The new file naming conventions for WinGet configurations files are:

- Use the `.winget` extension instead of `.dsc.yaml`. This allows user to run the configuration directly
  from the file explorer.
- The configurations should be placed in a `.config` directory in the root of the repository.

Reference: https://learn.microsoft.com/en-us/windows/package-manager/configuration/create#file-naming-convention

This commit also removes `allowPrerelease: true` directive from the `Microsoft.WinGet.DSC` resource.
The Microsoft.WinGet.DSC module is GA (stable) so the directive is no longer needed.
See https://www.powershellgallery.com/packages/Microsoft.WinGet.DSC/

For reference, maintainers may see these recommendations enacted in the following Microsoft repositories:

- WinGet CLI: https://github.com/microsoft/winget-cli/tree/master/.config
- WinGet Packages: https://github.com/microsoft/winget-pkgs/tree/master/.config
- WinGet Create: https://github.com/microsoft/winget-create/tree/main/.config
- PowerToys: https://github.com/microsoft/PowerToys/tree/main/.config
