wheel 0.47.0 caps its build requirement at "flit_core >=3.11,<4", but the
feed now ships flit-core 4.0.2, so python-wheel/host (and the whole python
host build-chain that depends on it) fails with "Missing dependencies:
flit_core<4,>=3.11". flit_core 4 builds wheel unchanged, so relax the upper
bound.
