Update to QT6 version, add darwin support

[LilleAila]

• Adds experimental QT6 support from Migrate to PySide6 openstenoproject/plover#1601
• Adds required packages to support darwin
• Updates from python311 to the standard python3, as the previous issues in nixpkgs have been fixed. This seems to also make the nixpkgs cache work properly.

Should be ready when the pull request in upstream is merged

Thanks for the pull request. Would it be possible to split this one into two separate pull requests? Would make it a bit easier to test one thing at a time.

It would, but the darwin part depends on qt6 first being merged, so i think it’s easier to develop both at the same time.

Currently using this flake on nixos fails to run with the following error message: "[MainThread] ERROR: Qt: Cannot mix incompatible Qt library (6.8.2) with this library (6.8.1)".

So I'm thinking it would likely be easier to get a linux build up and running first with qt6, then adding darwin support when that is working.

I don’t think that is related to darwin, but i can try building on nixos and see if i get the same error

No, that's not related to Darwin, it's just that I prefer pull requests solving one problem at a time.

It might be either due to some impurity creeping in, causing plover to run using system libraries, or due to some kind of dependency conflict.

It might be that the locked version of nixpkgs is causing something like that, where the system and plover qt versions are mismatched.

If i get time later i can split into a qt6 pr and a darwin pr based on it.

I don't get that error at all when i try running it. Is it just a warning, or does it just crash?

And i also found that there are no icons, and the tray icon does not show up on darwin.

Crashes (tested using latest nixos-unstable as the system distro)
