pyproject: update dependencies

- Require at least filelock >= 3.9. This is Debian's (bookworm) minimum and using that distribution as a standard, I think it's a good target as its where users are likely to meet the mesa requirement for DXVK, Python, and python-xlib. Users should strive to use the latest version available, but an actual hard minimum version for this application would be at least where the context manager protocol was supported which was 1.0.0. A better one would be at least the commit where the module's reported memory leak was addressed, which looks to be 3.0.7
