WordPress documentation is not including the (very useful) User Contributed Notes

# Documentation bug

## Summary
The WordPress documentation should include the section "User Contributed Notes", but currently that section is totally missing. That section is very useful as an information source, and is often the only spot where there are examples of the functions/filters in use.

## Actual style
* https://devdocs.io/wordpress/functions/the_custom_logo

## Expected style

* https://developer.wordpress.org/reference/functions/the_custom_logo/#user-contributed-notes

Compare the actual devdocs.io WordPress page for the_custom_logo with the expected developer.wordpress.org reference page, focusing on the missing User Contributed Notes section. Trace how WordPress function documentation pages are generated, then verify that the section appears with its examples on the affected pages.
