Bump --python-platform linux to manylinux_2_28 (#14300)

Right now, `--python-platform linux` to defaults to `manylinux_2_17`.
Defaulting to `manylinux_2_17` causes some problems for users, since it
means we can't use (e.g.) `manylinux_2_28` wheels, and end up having to
build from source.

cibuildwheel made `manylinux_2_28` their default in
pypa/cibuildwheel#1988, and there's a lot of
discussion in pypa/cibuildwheel#1772 and
pypa/cibuildwheel#2047. In short, the
`manylinux_2014` image is EOL, and the vast majority of consumers now
run at least glibc 2.28 (https://mayeut.github.io/manylinux-timeline/):

Note that this only changes the _default_. Users can still compile
against `manylinux_2_17` by specifying it.
