Pin PyQt6 back on Ubuntu 20.04

QuLogic · QuLogic · commit 99eaf725ec58 · 2024-07-19T19:19:12.000-04:00
The 6.7.1 wheels on PyPI do not conform to manylinux 2.28 due to
requiring glibc 2.35 symbols, and cannot be loaded on Ubuntu 20.04,
which has glibc 2.31. So we need to pin that back to avoid test
failures.
