Look at:

• https://docs.python.org/3.13/whatsnew/3.13.html#pending-removal-in-python-3-14
• https://docs.python.org/3.13/whatsnew/3.13.html#pending-removal-in-python-3-15
• https://docs.python.org/3.13/whatsnew/3.13.html#pending-removal-in-python-3-16
• https://docs.python.org/3.13/whatsnew/3.13.html#pending-removal-in-future-versions

Each bullet point begins with the relevant module name, and the bullets are alphabetised.

Let's do the same for:

• https://docs.python.org/3.13/whatsnew/3.13.html#deprecated
• https://docs.python.org/3.13/whatsnew/3.12.html#deprecated
• https://docs.python.org/3.13/whatsnew/3.12.html#pending-removal-in-python-3-14
• https://docs.python.org/3.13/whatsnew/3.12.html#removed

I made some changes on the page What’s New In Python 3.13-Deprecated. Is it the way we want? If it is OK, I am glad to modify the other pages

I found some changes cannot be classified into spesific modules so I just left them alone.
