CI: rosdep installation of ros-humble-rmw-connextdds fails

[rhaschke]

@ros-planning/moveit-maintainers: do you know how to fix the following rosdep install failure in humble-release:

  executing command [apt-get install -y -qq ros-humble-rmw-connextdds]
  rti-connext-dds-6.0.1: RTI license agreement for non-commercial and pre-commercial use NOT accepted.
  E: Sub-process /usr/bin/dpkg returned an error code (1)
  ERROR: the following rosdeps failed to install
    apt: command [apt-get install -y -qq ros-humble-rmw-connextdds] failed

Obviously, the installation of the DDS middleware requires explicit confirmation to the license agreement. The option -y doesn't work as expected, maybe because one needs to scroll through several pages first.
Where does this requirement come from?

Don't have the full background, but if this has to do with a CI image we can control, there seems to be an environment variable that can be set.

Thanks for the hint! I filed moveit/moveit2#2790 to fix CI.

P.S.: I couldn't figure out yet, which dependency pulls in rmw-connextdds. MTC and MoveIt don't explicitly require it.
