ENH: switch long argument list to mandatory kwarg for votable #17224

It's too late for this in the 7.0 release cycle (as we want to avoid unnecessary downstream breakage), but removing the option for a very long list of positional would be nice.

Note, this will need someone who knows about votables as a lot of these parameters are already a set of field and attr lists, sometimes with seemingly present duplicates, so where to put the limit for the positional and kwag list may require some familiarity with the standards, etc.
