Updates for glue-qt

[Carifio24]

This PR will update glue-wwt to be compatible with the new glue-qt package, once we're ready for that (see glue-viz/glue#2431). If the locations of things change, I will update here.

To do:

• Update package setup

I've now released glue-qt v0.1.0 so you should be able to add that package as a dependency here (at least for the testing - we probably don't want it to be a compulsory runtime dependency in case glue-wwt is used in jupyter for instance).

[Carifio24]

@astrofrog I've added glue-qt as a dependency for the test and qt install options (and also moved qtpy). I've also bumped the minimum Python version from 3.7 -> 3.8 to match glue-core, and swapped out the 3.7 CI for 3.11 as well. Let me know if you see any issues with those changes.

Looks good to me! Feel free to merge once you are happy with it
