for pandas.util.hash_pandas_object:
- Add parameter description to obj parameter
- Correct the Returns section
	- Change the type line to correctly callout 'Series' type
	- Update return description to describe the type contained in the Series
- Add See Also section
- Removed from code_checks.sh

for pandas.Timestamp.resolution
- Removed from code_checks.sh (I don't believe more work is needed because resolution is no longer a function, see #29910
