subtracing a TimeStampSeries from a Timestamp not supported

[Dr-Irv]

Describe the bug
Type checking missing for Timestamp - TimestampSeries

To Reproduce

import pandas as pd
ts1 = pd.to_datetime(pd.Series(["2022-03-05", "2022-03-06"]))
assert isinstance(ts1.iloc[0], pd.Timestamp)
one_ts = ts1.iloc[0]
reveal_type(one_ts - ts1)

revealed type should be TimedeltaSeries.

Note that ts1 - one_ts works fine.

Need to add an overload in pandas-stubs/_libs/tslibs/timestamps.pyi

Please complete the following information:

• OS: Windows
• OS Version 11
• python version 3.10
• version of type checker pyright 1.386
• version of installed pandas-stubs - development copy
