[BUG] use of incomplete type PyFrameObject in __Pyx_PyFrame_SetLineNumber/__Pyx_AddTraceback

[gastineau]

Describe the bug
A clear and concise description of what the bug is.

In generated c code, the generated macro __Pyx_PyFrame_SetLineNumber still uses fields of PyFrameObject, but PyFrameObject has moved to internal API.
I was fixing the reported bug https://bugzilla.redhat.com/show_bug.cgi?id=2062338
but it appears that the problem comes from the generated code by cython.

python 3.10 and cython works fine on this code.

After removing some warnings, I still obtain this error with the last docker image of python : 3.11-rc-bullseye

I'm pretty sure this was fixed in 7537910 and afc00fc (depending on the Cython version) - it just hasn't made it into a release yet.
