Migration to qt6 #117
Description
qt5 is deprecated, EOL and unsupported.
I think we already explored migration on qt6 based bindings as part of #104, but there were some blockers, mostly on the conda-forge side:
- pyqt6 : Missing in conda-forge, see Upgrade to PyQt6 6.8.1 conda-forge/pyqt-feedstock#145
- pyside6 : qt-webengine in general is missing, see qt6-webengine conda-forge/qt-webengine-feedstock#42
