Don't check for frame annotation completeness for Python 3.11 and later (#87)

mdickinson · web-flow · commit 9909dea720b6 · 2023-10-07T13:15:36.000+01:00
This PR skips frame annotation completeness tests for Python >= 3.11. Python 3.11 added a reference to the function from the frame (see python/cpython#29595), but didn't expose that reference at Python level.
