OpenAPI files for AI Models

[dylan-apex]

If you want to use a more advanced model with Agent Builder in GCP, then you need to generate an OpenAPI YAML or JSON file and upload it as a tool.

This is definitely something that people can do individually, but it would be beneficial to everyone if there were ready-made files and examples in the cookbook that people could grab quickly. I assume that there are copies of this floating around the Google-universe since I saw it often during Google Next, someone just needs to grab them and make them publicly available.
