Rename arguments of list_evaluations to indicate they expect lists of ids

[PGijsbers]

See also #796. It was a step forward, but the argument names still don't convey that we are looking for a list (i.e. argument name should be plural) or ids as opposed to OpenML objects (e.g. by a suffix _id).

I would argue that we also should update the type hints (to Optional[List[Union[str, int]]]) and add parameter descriptions in the docstring.
