Support PEP 730 (Adding iOS as a supported platform)

[di]

PEP 730 is accepted, https://peps.python.org/pep-0730/, PyPI needs to be updated to permit the additional wheel tags: https://peps.python.org/pep-0730/#packaging

The list of supported platform tags is currently here:

warehouse/warehouse/forklift/legacy.py

Lines 98 to 187 in 6792d38

	# Wheel platform checking
	# Note: defining new platform ABI compatibility tags that don't
	# have a python.org binary release to anchor them is a
	# complex task that needs more than just OS+architecture info.
	# For Linux specifically, the platform ABI is defined by each
	# individual distro version, so wheels built on one version may
	# not even work on older versions of the same distro, let alone
	# a completely different distro.
	#
	# That means new entries should only be added given an
	# accompanying ABI spec that explains how to build a
	# compatible binary (see the manylinux specs as examples).
	# These platforms can be handled by a simple static list:
