Request: Build PyQt6-Qt6 Linux wheels as manylinux1

[Carlos Pereira Atencio]

Hi Florian,

Yes, I meant PyQt6->manylinux1 and PyQt6-Qt6->manylinux_2_28.

Thanks for the clarification of where the limitation comes from! That's a
pity, as Ubuntu 18.04 is still supported by Canonical for another year, but
ships glibc 2.27, so a Python app using the PyPI PyQt6 wheels will only be
compatible out of the box with Ubuntu 20.04+.

Cheers,
Carlos
