[hugovk]

cibuildwheel v2.23.0 (#8785) now also builds PyPy3.11 (https://github.com/pypa/cibuildwheel/releases/tag/v2.23.0).

https://github.com/python-pillow/Pillow/actions/runs/13608693136 created PyPy3.10 and 3.11 wheels for all:

We already exclude PyPy3.9 explicitly, so we can make change this macOS 10.15 x86_64 wildcard from pp310* to pp3*.

This then also builds this wheel:

./dist-macos-13-10.15-x86_64/pillow-11.2.0.dev0-pp311-pypy311_pp73-macosx_10_15_x86_64.whl
