Link in the "Bugs fixed" section of the 5.1.0 change log is not correct

Describe the bug

The bugs fixed section of the 5.1.0 Changelog includes this line:

• #10031: py domain: Fix spurious whitespace in unparsing various operators (+, -, ~, and **). Patch by Adam Turner.

The problem is that the text "py domain: Fix spurious whitespace in unparsing various operators (+, -, ~, and **)" does not match the pull request #10031.

I noticed this because I was checking to see which release contains https://github.com/sphinx-doc/sphinx/pull/10551. I don't see any mention of that pull request in the change log.

PR welcome, otherwise I'll get to it at the weekend most likely. Thanks for reporting!
