BUG: avoid DeprecationWarning when the Series has index as list of Series (pandas-dev#55395)

* BUG: avoid DeprecationWarning when the Series has index as list of Series

* hasattr(type(obj), '_data') not working as expected, for instance 'pytest pandas/tests/indexes/period/test_period.py::TestPeriodIndex::test_with_multi_index'

* adopt jbrockmendel suggestion: runtime import ABC{Index, Series}

* exclude ABCMultiIndex; move changelog to 2.1.3

* fix changelog order

* moved changelog 2.1.3 -> 2.1.4
