Fix/update CI

Some of the software installed on DAS-6 has changed, requiring the scripts that load environment modules for the tests on DAS-6 to change accordingly.

In the process, some dependencies have been updated to more recent versions. Since the CI on Docker was still using Ubuntu 20.04, it has been updated to use Ubuntu 22.04. A number of issues were identified in the process and fixed along the way.

At the moment, tSinglePointSource and tGridDegrid do not seem to work with the latest version of WSClean (v3.4) due to conflicts with polarizations and/or stokes counts. Fixing this is beyond the scope of this MR and indstead, slightly outdated versions of software are used: WSClean v3.3, DP3 v5.4 and Everbeam v0.4.0.
