github actions: user newer cython versions

`setup.py` is pinning to use `Cython>=0.20,!=0.25,<0.30`
code generated form those old versions is not compiling anymore with python3.13

in turn it cause libev part to be missing in the driver, which surface
other issue with asyncio eventloop we currently use as default

in this chnage we pin to newer version of cython when we build
the wheel
