Bump default OpenFOAM version to v2306

[MakisH]

• Replaces the default OpenFOAM version from v2212 to v2306 in the README and default CI workflow, and switches the default Ubuntu version to 22.04
• Adds v2306 and Ubuntu 22.04 to the custom build workflow
• Replaces the default preCICE version from v2.3.0 to v2.5.0 in the custom build workflow (not that it matters, but v2.3.0 was a strange default)

A separate PR in the tutorials will update the Quickstart.

TODO list:

• I updated the documentation in docs/
• I added a changelog entry in changelog-entries/ (create directory if missing)

Somehow, I always get an error that it cannot find the respective openfoam2306-dev package. Both for Ubuntu 22.04, as well as for 20.04. And same for openfoam2212-dev.

This looks strange, since previously we were building with openfoam2212-dev on Ubuntu 20.04, so at least this combination should work...

There may be an issue with the package repository. Explicitly calling apt update, I get:

If I go to https://sourceforge.net/projects/openfoam/files/repos/deb/dists/jammy/main/binary-all/ and download Packages.gz, I get the expected sha256sum. If I follow the (mirror?) link that APT reports, I get the reported one. The modification date seems to be different.

@olesenm does this issue sound familiar? I can imagine that Sourceforge has not updated some mirrors or similar.

[olesenm]

looks like a bad value there - will have to check with andy if all of the packages were sync'd across.

The modification date should be correct. I updated rebuilt the listings after including bookworm (debian) into the repos.

@olesenm unless you triggered something, time seems to have fixed the problem already. Thanks for the answer!
