Bug description

As of today, the CI fails while Swig compiles icub.i for python:

It seems that there are problems dealing with yarp::conf::createVocab32().

I guess ubuntu-latest switched from being 22.04 to 24.04 . Ubuntu 24.04 comes with swig 4.2.0, that has some known bugs that are solved in later version of 4.2.1 , for that we are installing a custom (private, so it does not interfere with the rest of the system) swig in the robotology-superbuild when building on 24.04 .

The quickest fix is to go back to 22.04, otherwise to test with 24.04 with apt dependencies we need to manually install a newer swig version.

Thanks @traversaro 👍🏻

Here's for reference the superbuild machinery you mentioned:

If updating via apt is quick (perhaps through a backport), I'll do that, otherwise I'll switch it back to 22.04.

Fallback to Ubuntu-22.04 for now.
