I think you're right that this version is fine for Humble.

REP 2000 lists a bunch of CMake versions for Humble for all the target platforms, and they're all definitely > 3.8: https://www.ros.org/reps/rep-2000.html#humble-hawksbill-may-2022-may-2027. However, it's not that CMake 3.8 is necessarily deprecated: I believe it's actually about declaring a minimum version that's too low (e.g., 3.8) with a newer version of CMake, but Humble (Ubuntu 22.04) has an older version of CMake.

Then I'd just leave this as-is.
