Fixed Toast.getView() and Html.fromHtml() is deprecated

* We already handled the deprecation of `fromHtml`, we have a string's extension function to handle the this so we are now using that function.
* Since `Toast.getView()` is no longer supported after Android 11 (it always returns null on Android 11 and above devices), we no longer need to show the toast on the ZIM file that is clicked by the user for UI enhancement. Therefore, we have removed this function and are now using the context class extension function to display the toast message.
