Tested with ros-rolling-zenoh-cpp-vendor package on noble and gz-transport is able to find zenohc and zenohcxx with this package.

Not related to code changes but I would prefer if we can pick an stable ROS release instead of Rolling so we avoid future version bumps of Zenoh that we can not control. If I checked it correctly, both rolling and jazzy are shiping Zenoh v1.3.2 ros2/rmw_zenoh@3e19ec7

ok tested with ros-jazzy-zenoh-cpp-vendor package and that works too so added ros-jazzy-zenoh-cpp-vendor to packages-noble.apt

Added before_cmake.sh to set up ros env on ubuntu github actions. Noble CI should be working now, see cmake output in build

  -- defined lib target zenohcxx::zenohc for zenohc::lib
  -- Looking for zenohcxx and zenohc - found

Jammy CI is not officially supported so removed in #616

As discussed in PMC meeting, we can move to ros-kilted-zenoh-cpp-vendor once Kilted is out, which is in ~1 month from now.

given that Ubuntu noble github action is working now, I'll merge this first so we can start testing.
