Minor improvements to deezer plugin typing.

Description

Added some more typehints to deezer plugin.

I know, it is properly not used much and we don't even have test for the deezer plugin but I want to make this a bit more maintainable, mainly to prepare for #5787 and make migration a bit easier.

• The docstring for track_for_id still references a track_data parameter that was removed from the function signature. Please update the documentation to reflect the current parameters.

    :param track_data: (Optional) Simplified track object dict. May be provided instead of ``track_id`` to avoid unnecessary API calls.
