Migrate Linux CI to the ubuntu-24.04 GitHub Actions runner

The ubuntu-20.04 runner is due to be deprecated on 2025-02-01 and
unsupported by 2025-04-01.

The ubuntu-24.04 runner does not include cbindgen, so it's now installed
using apt.

GCC 10 doesn't support the newer libtbb that is in Ubuntu 24.04's apt
repositories, so update to GCC 13.

The behaviour of std::filesystem::equivalent changed at some point
between GCC 10 and GCC 13, so the tests have been updated to reflect
that.
