supportedFileExtensions(): Promise<Readonly<{ extension: string; priority: number }>[]>
Resolves to an array of file extensions - priority pairs supported by the Mini Browser.
The file extensions start without the leading dot (.) and should be treated in a case-insensitive way. This means,
if the Mini Browser supports ['jpg'], then it can open the MyPicture.JPG file.
