TST: rdivmod on EA Arrays

[jreback]

xref #23271

I think we need to add a test case for rdivmod as its now defined on Series.

There are at least already tests for Series with scalar (but not Series/Series or Series/array), it seems:

	s = pd.Series(data)
	self._check_divmod_op(s, divmod, 1, exc=self.divmod_exc)
	self._check_divmod_op(1, ops.rdivmod, s, exc=self.divmod_exc)
