@rhshadrach Can you please help me with this Doc string validation error?

Error: /home/runner/work/pandas/pandas/pandas/io/excel/_base.py:1530:GL09:pandas.ExcelFile.parse:Deprecation warning should precede extended summary

Where should I put the deprecation message in the Doc string? I think the linter is thinking you are deprecating the method; even though it's somewhat of a false positive, it does seem better to have the deprecation warning above the extended summary, i.e. 4 lines above where it is now.
