rosdep install fails on macOS with ROS2 Humble (RoboStack) due to find-object-2d dependency

[yyuunn922]

The installation failed while proceeding according to the manual and I cannot proceed.

When running rosdep install on the humble branch of the xarm_ros2 repository, the process fails with a "package not found" error for ros-humble-find-object-2d. This issue prevents me from installing all required dependencies and building the workspace.

`
cd ~/dev_ws/src/
rosdep init
rosdep update

rosdep install --from-paths . --ignore-src --rosdistro $ROS_DISTRO -y
`

Actual Behavior
The command fails with the following error output:

Hi @yyuunn922, are you using Mac (osx-arm64)? We only tested with Ubuntu Linux with x86 hardware and it worked fine. We are not sure about the ROS 2 support level of other platforms, or with conda.

Maybe you can try installing this package from source into your workspace first, refer: https://github.com/introlab/find-object
