docs: Set the finger number to button number mapping for tap-to-click.
  
  		The default mapping on most devices is to have a 1, 2 and 3 finger tap
  		to map to the left, right and middle button, respectively. A device may
  		permit changing the button mapping but disallow specific maps. In this
  		case :attr:`~libinput.constant.ConfigStatus.UNSUPPORTED` is returned,
  		the caller is expected to handle this case correctly.
  
  		Changing the button mapping may not take effect immediately, the device
  		may wait until it is in a neutral state before applying any changes.
  
  		The mapping may be changed when tap-to-click is disabled. The new
  		mapping takes effect when tap-to-click is enabled in the future.
  
  		If :attr:`finger_count` is 0, this method raises :exc:`AssertionError`.
  
  		Args:
  			button_map (~libinput.constant.TapButtonMap): The new
  				finger-to-button number mapping.
  		Returns:
  			~libinput.constant.ConfigStatus: A config status code.
  		Raises:
  			AssertionError
