gh-95914: Add missing PEPs to the Summary section of 3.11 What's New by CAM-Gerlach · Pull Request #95916 · python/cpython
As described in #95914, the Summary section of the What's New in Python 3.11 document is missing most of the PEPs implemented in that release, unlike e.g. the 3.10 What's New. Therefore, this PR adds the missing PEPs, following the categories from previous What's New documents.
Also, to clean things up a bit and avoid too many categories with only a single item, it moves the -P item to the added Interpreter Changes category.
