DOC: Fix docstrings error GL07 - Sections are in the wrong order
When checking for errors with ./scripts/validate_docstrings.py, There is an error that comes up:

GL07
'Sections are in the wrong order. Correct order is: ' '{correct_sections}'

I worked on this and will create a pull request for this issue shortly to go into more detail on what I fixed.
