DOC: fix docstring validation errors for pandas.core and pandas.errors

[sunlight798]

follow up on issues #59698, #59458 and #58063 pandas has a script for validating docstrings:

pandas/ci/code_checks.sh

Lines 86 to 100 in b0192c7

	-i "pandas.core.groupby.DataFrameGroupBy.plot PR02" \
	-i "pandas.core.groupby.SeriesGroupBy.plot PR02" \

Currently, some methods fail docstring validation check. The task here is:

• take 2-4 methods
• run: scripts/validate_docstrings.py <method-name>
• run pytest pandas/tests/scalar/test_nat.py::test_nat_doc_strings
• fix the docstrings according to whatever error is reported
• remove those methods from code_checks.sh script
• commit, push, open pull request

Example:

 scripts/validate_docstrings.py pandas.Timedelta.ceil

pandas.Timedelta.ceil fails with the SA01 and ES01 errors

################################################################################

2 Errors found for `pandas.Timedelta.ceil`:
        ES01    No extended summary found
        SA01    See Also section not found

Please don't comment take as multiple people can work on this issue. You also don't need to ask for permission to work on this, just comment on which methods are you going to work.
