As you can see in this PR https://github.com/ros-controls/gazebo_ros2_control/pull/266 where this change was included, the CI is compiling the code (it's red because one test is failing)

There are some new breaking changes in ros2_control which means you need to wait until the next Humble sync (which I think it was out last week) or you can compile ros2_control from source

[uiinlee]

Thank you for your response. Then would it be advisable for me to wait until the next set of changes?

[ahcorde]

if you run:

sudo apt-get update
sudo apt-get upgrade

the you should be able to compile it
