DOC: Added check for standard pandas reference

[joybh98]

• xref DOC: Standardize references to pandas in the documentation #32316
• tests added / passed
• passes black pandas
• passes git diff upstream/master -u -- "*.py" | flake8 --diff
• whatsnew entry

As suggested by @datapythonista , I've added checks in ci/code_checks.sh to look if the pandas is being referenced in a standardized way i.e pandas, not pandas or Pandas

I'm getting ./ci/code_checks.sh: line 243: RET: command not found, I can't understand why I'm getting this error. All the checks are using it.

EDIT : Fixed the error mentioned above, pushing the changes

Once again, can you check locally if things are working? This is my 10th time reviewing this PR and it's obvious once more that this is not working. There are more than 100 cases of the work Pandas in doc/, and your changes are not detecting those. No need for your PRs to be perfect, but can you please stop proposing changes that you didn't try locally even once to see if they run without errors or they make sense? Thank you
