Documentation rendering improperly for keys function.

[kattni]

The list of properties in the keys documentation renders with the final member of the list as bold: https://docs.circuitpython.org/projects/macropad/en/latest/api.html#adafruit_macropad.MacroPad.keys

The solution that worked elsewhere for me was to indent the wrapped text below the initial line with two spaces only, e.g. update it to match what is shown here:

        * ``released``: ``True`` if the event is a transition from pressed to released.
          ``released`` is always the opposite of ``pressed``; it's provided for convenience
          and clarity, in case you want to test for key-release events explicitly.

If what is shown above is not clear, remove the indentation on the wrapped text back to equal with the *, and then indent the wrapped text by only two spaces.
