Make python 3.13 version of virtual packages the default. - batch 04

[smoser]

Make python-3.13 version of PYPI_PKG provide virtual py3-PYPI_PKG

This just makes the python v3.13 version of a package the highest
version. So now, if you do apk add py3-appnope, you'll get
py3.13-appnope where before you would get py3.12-appnope.

The 'set-313.sh' script used to do this looks like:

#!/bin/sh -e
r=' \(["'\'']*3[.]13["'\'']*\): \(["'\'']*\)[0-9]\+\(["'\'']*\)'
n=313

files=$(git grep -l "$r")
set -- $files
echo "$# files"
sed -i -e "s,$r, \1: \2${n}\3," "$@"
wolfictl bump "$@"
