chore:Fix docs build by bump build system

[Czaki]

The build docs on ReadTheDocs fail with:

 Resolved 140 packages in 1.57s
error: Distribution `pyqt6-qt6==6.10.1 @ registry+https://pypi.org/simple` can't be installed because it doesn't have a source distribution or wheel for the current platform
hint: You're on Linux (`manylinux_2_31_x86_64`), but `pyqt6-qt6` (v6.10.1) only has wheels for the following platforms: `manylinux_2_34_x86_64`, `manylinux_2_39_aarch64`, `macosx_10_14_x86_64`, `macosx_11_0_arm64`, `win_amd64`, `win_arm64`; consider adding "sys_platform == 'linux' and platform_machine == 'x86_64'" to `tool.uv.required-environments` to ensure uv resolves to a version with compatible wheels 

This change build OS version to have a more recent glibc version.
