DOC: Fixing SA04 errors as per #25337
- [ ] Went through every file and filled in missing references in See Also section
- [ ] Updated code_check.sh to reflect it.

To do this I went through every file and corrected the SA04 errors.

When executing "validation_docstring.py" as per the "Pandas documentation validation errors" page, SA04 errors were still appearing but I haven't been able to locate them. Assistance may be required.
Hello @Sedosa! Thanks for submitting the PR.
