I removed the CI files so this does not trigger a build to ease things. So please review the individual commits as the CI changes are not visible. |

Using Qt6 seems to switch the whole project to C++17 leading to unexpected clang-tidy warnings and the runtime of the clang-tidy step seems to be balloon because of it. Also there seems to be no Qt6 on ubuntu 20.04 so deprecating Qt5 should be fine but dropping it (even though EOL) doesn't seem like an option in the near future. |

Qt 5.15 will be EOL on May 26 so we should start switching away from it. We already have issues with many of the previous versions and qmake on legacy distros so we should cut that off.
I will add a Qt6 release build for Windows in another PR so it can be tested. We should switch to it as the delivered build after the next release and stop using Qt5 altogether in the CI in the release afterwards (that would get rid of several build steps). We could leave it so you could still try to build it but no longer support it so it is up to the user to get it to work before removing it completely later on.
