dict argument to `pd.Series` constructor should allow `Timestamp` and `tuple` as keys

[Dr-Irv]

Additional migration issues for the pd.Series constructor involve passing a dictionary. It fails with a Timestamp or multi-index key whereas before it did not:

sr1 = pd.Series(
        {
            pd.Timestamp(2023, 1, 2): "b",
        }
    )

    sr2 = pd.Series(
        {
            ("a", "b"): "c",
        }
    )

test.py:172: error: Need type annotation for "sr1"  [var-annotated]
test.py:174: error: Dict entry 0 has incompatible type "Timestamp": "str"; expected "str": "ndarray[Any, Any]"  [dict-item]
test.py:178: error: Need type annotation for "sr2"  [var-annotated]
test.py:180: error: Dict entry 0 has incompatible type "Tuple[str, str]": "str"; expected "str": "ndarray[Any, Any]"  [dict-item]

Might be best to allow Hashable as the dict key.
