Fix Qt version mismatch by making quickshell follow our nixpkgs

- Make quickshell input follow our nixpkgs to ensure Qt version consistency
- Fixes 'Cannot mix incompatible Qt library (6.9.1) with this library (6.9.0)' error
- Resolves weather widget enable crashes due to Qt version conflicts

This ensures quickshell is built with the same Qt version (6.9.1) as our other
Qt packages, preventing runtime library incompatibility issues.
