Channel names are Beta, Dev, and Canary. If an override exists for the browserExecutableFolder or the channel preference, the override is used. If an override is not specified, then the parameter value passed to getAvailableVersion is used. Returns null if it fails to find an installed WebView2 runtime or non-stable Microsoft Edge installation.
