Fix CI

[traversaro]

Fixes:

• I was passing the docker image name also to runs-on parameter, resulting in the job waiting forever.
• Furthermore, I was not passing -y to apt-get install.
• Furthermore, on 20.04 the tzdata was made the install hang, see https://github.com/ami-iit/meshcat-cpp/pull/5#issuecomment-1489908674
• We also a conda CI problem, that we workarounded, see https://github.com/robotology/robotology-superbuild/issues/1375 for details

macOS fails with

/Users/runner/miniconda3/envs/test/include/boost/container_hash/hash.hpp:132:33: error: no template named 'unary_function' in namespace 'std'; did you mean '__unary_function'?
        struct hash_base : std::unary_function<T, std::size_t> {};

As explained in https://github.com/Microsoft/cpprestsdk/issues/954 unary_function was removed in C++17

Ubuntu 20.04 is not passing as it hangs on:

We need this: https://github.com/robotology/robotology-superbuild/blob/2cdc52d76414b6a0de56ced1945a67741cb42271/.ci/install_debian.sh#L6 .

That is tracked in https://github.com/robotology/robotology-superbuild/issues/1375, I added a workaround also for that.

Ok, all CI is green, probably we can just squash with merge as it is just a bunch of CI workarounds.

(By the way: Ubuntu 20.04 is happy with our use of C++20 : ) )
