Add version constraint to all Qt modules

rel.mo always points to the latest stable version, but we have different runtimes for every minor Qt version 6.5, 6.6 etc.

I forgot about this...this was fine because 6.6.0 didn't exist. Now it tries to update to https://download.qt.io/official_releases/qt/6.5/6.6.1/foo because $version points to the latest one, but under 6.5 there is no tarball for 6.6.1

The constraint is the next major.minor of Qt, beta/rc doesn't matter because stable only is enabled.
