Unify PickNik name in copyrights

[tylerjw]

Description

Various copyrights mention PickNik Robotics (these are my fault), PickNik LLC (from moveit1, we should fix these there too), PickNik Consulting (only one of these). There is a legal requirement that these are a legal name. This fixes that.

moveit_servo tests continue to be flaky, re-running jobs. We should probably fix the flakyness of those before trying to release for foxy or it will probably plague the official buildfarm.

Edited: I think we should use "PickNik Inc." and not "PickNik, Inc."

With this search
grep --ignore-case -r -P "PickNik(?! Inc.)" . | grep -v "picknik.ai"

I picked up a few things that should be resolved with
findreplace "PickNik, LLC" "PickNik Inc."
findreplace "PickNik nor" "PickNik Inc. nor"
findreplace "PickNik, Inc" "PickNik Inc"
