Add `source` entry for ros2_openai_server (jazzy)

[AndyZe]

This is a new package so I'm adding the source entry per https://docs.ros.org/en/jazzy/How-To-Guides/Releasing/Release-Team-Repository.html#create-a-new-release-repository

OpenAI is an organization, the name of this package seems a bit misleading on what the actual service is or what is calling.

I'd be fine with chatgpt_server if that floats your boat. I'm aware that I should drop ros2_ from the front

OK, I can live with robosoft_openai_server or robosoft_openai
