upstream: ros2_control deprecation replace fake with mock

[moriarty]

This fixes the depreciation warning introduced upstream: https://github.com/ros-controls/ros2_control/commit/9d5d524c05e48035427f564d3a0e00c127e021e5

Found a branch from @sea-bass and opening a Draft PR.

Since this package hasn't been released into humble yet I will try to get this change in. It is built on top of a branch from @eholum that also hasn't been merged.

[sea-bass]

@moriarty branch is rebased on main and contains just the changes we care about.

Again, if we can possibly cut a humble branch before this PR goes in and keep this one going forward as main, that would probably be best in terms of not breaking stable releases.

@sea-bass yeh that makes sense, I'll first do a 0.0.1 release without this change and then merge this after and create a humble branch.
