DOC: fix EX03 errors in docstrings - pandas.Series.to_latex, pandas.read_pickle, pandas.DataFrame.to_latex, pandas.core.resample.Resampler.pipe 
Checked if validation docstrings passes for :

1. scripts/validate_docstrings.py --format=actions --errors=EX03 pandas.Series.to_latex                       
2. scripts/validate_docstrings.py --format=actions --errors=EX03 pandas.read_pickle                           
3. scripts/validate_docstrings.py --format=actions --errors=EX03 pandas.DataFrame.to_latex                    
4. scripts/validate_docstrings.py --format=actions --errors=EX03 pandas.core.resample.Resampler.pipe          

OUTPUT:

1. scripts/validate_docstrings.py --format=actions --errors=EX03 pandas.Series.to_latex

Looks like the check for [macos-latest actions-312.yaml](https://github.com/pandas-dev/pandas/actions/runs/7497789678/job/20411908880?pr=56843#logs) is failing, I cannot seem to find a way to re run the check. Any guidance would be appreciated.

EDIT:
I was able to re-run from my local machine but the "Checkout" phase of [macos-latest actions-312.yaml](https://github.com/pandas-dev/pandas/actions/runs/7497789678/job/20411908880#logs) is still failing with "Error: fatal: unable to access 'https://github.com/pandas-dev/pandas/': Could not resolve host: github.com"

FINAL EDIT: 
Merging main branch back into my branch resolved this issue and after running the checks again, All checks have passed.  @datapythonista I've responded to your comments and updated my code. Can you please review again when you have a moment? Thanks for all the detailed feedback. If any improvements are still needed I'm happy to revisit any issues that you find.  Thanks @jordan-d-murphy, great work
