Allow preventing text drag

[fantactuka]

This PR adds input event to REMOVE_TEXT_COMMAND to allow preventing text drag by simple plugin:

useEffect(() => {
  const preventInputEvent = (event: unknown, inputType: string) => {
    if (event instanceof InputEvent && event.inputType === inputType) {
      event.preventDefault();
      return true;
    }
    return false;
  };

  return mergeRegister(
    editor.registerCommand(
      CONTROLLED_TEXT_INSERTION_COMMAND,
      event => preventInputEvent(event, 'insertFromDrop'),
      COMMAND_PRIORITY_HIGH,
    ),

    editor.registerCommand(
      REMOVE_TEXT_COMMAND,
      event => preventInputEvent(event, 'deleteByDrag'),
      COMMAND_PRIORITY_HIGH,
    ),
  );
}, [editor]);
