Fix syntax

[sjahr]

Description

Replace a comma with a semicolon. I am a little bit confused, why did this build before and why doesn't CI complain about this?

Checklist

Wow.

Wow indeed, I should investigate why CI didn't catch this.

But this

hp_action_client_ = rclcpp_action::create_client<moveit_msgs::action::HybridPlanner>(node_, "run_hybrid_planning"),

builds in my local setup too, so maybe CI is fine.

It builds fine because similarly, this is valid c++ syntax:

a = 2, b = 3;

The comma operator can be used to separate multiple assignment statements, there is no requirement that you have to put a semi-colon at the end of a line, only that you have to finish each statement with them.

Ahh, thanks for making this clear, I totally forgot about this syntax option. Should we merge it anyways for uniformity and to avoid further confusion?
