Update Github Actions CI

[joergbrech]

Fixes #1006

• Updated action versions to update Node.js

• The updated codecov action now needs a token to upload coverage reports. This has been added. At first sight it seems like the coverage report drops by 26.3%, presumably because only the unit test report is considered, and not the integration test report. Not sure why, need to investigate.

• Needed to downgrade macos version, because the latest runner updated to the new arm architecture which is not supported by our build system yet (another To-Do for us)

• Needed to update boost and gradle to build on macos.

  • boost is now added to a dependency installed with conda.
  • The update of grade auto-changed some of the files in the bindings/java directory.

• The update of boost had a dependency conflict with qt, so I needed to update qt

     The following packages are incompatible
       ├─ libboost 1.82.0**  is installable and it requires
       │  └─ icu >=73.1,<74.0a0 , which can be installed;
       └─ qt 5.9.7**  is not installable because it requires
          └─ icu >=58.2,<59.0a0 , which conflicts with any installable versions previously reported.

  In addition, I now got a weird ninja error on all platforms: ninja: error: build.ninja:6801: multiple outputs aren't (yet?) supported by depslog; bring this up on the mailing list if it affects you. So I updated ninja

• The newer Qt Version distributed with Anaconda was apparently build with gcc>9, which resulted in a GLIBC and GLIBCXX conflict on the Ubuntu 20.04 runner that only has g++ 9.3 installed. To save myself the trouble, I just removed ubuntu-20.04 from the build matrix. As of now, ubuntu-latest and ubuntu-22.04 are the same, but I suppose github will soon switch ubuntu-latest to ubuntu-24.04 and then we will be testing two different linux configs again.
