Replace previous Google.Chrome version on update

[UnownPlain]

Google.Chrome uses a vanity URL so the previous version should be replaced when it is updated.

[SpecterShell]

The feature (replacing the previous version) is disabled for this package by intention due to a bug in the winget-pkgs validation pipeline.

Another package Google.ChromeRemoteDesktopHost depends on Google.Chrome. When a package that other packages depend on has only one version available, removing or replacing that version would trigger a validation error.

For example: microsoft/winget-pkgs#248546
