DEPR: enforce deprecation of old set_axis signature
lgtm ping on green. We're running out of things to remove in #6581!  One thing there that could use a look from someone more experienced than me is the how/fill_method/resample one (now top of this list).  My last attempt to enforce it didn't go well. > We're running out of things to remove in #6581!
