Add PyPy3.11 windows wheel build

[mattip]

In #125 support was added for PyPy3.11, but something didn't work in windows, there was this error:

--- stderr
  error: failed to generate python3.dll import library
  caused by:
    - 0: Unsupported PyPy version

Perhaps connected to https://github.com/crate-py/rpds/blob/c89ed6d5082cf73b6c2822dc00edbec35650a55f/Cargo.toml#L16-L18

I will try to take a look, please assign the issue to me.
