Update adhoc-api to version 2.0.2 which adds support for example curation

Changes

• examples are no longer included in the documentation text body
• examples get their own field in the api.yaml
• examples are stored in examples.yaml instead of examples.md so that they can follow a common structure and be loaded via the !load_yaml tag
• modified yaml loading:
  • !load tag replaced with !load_txt for loading raw text content from a file
  • added !load_yaml tag for loading structured content from a yaml file
  • added !load_json tag for loading structured content from a json file
  • removed string interpolation by default, and added !fill tag to mark which strings should be interpolated
• added 2 LLM configs to adhoc-api:
  • curator: agent that identifies if any of the examples are a perfect match or close match for the current query
  • contextualizer: agent that converts the current query to a context free version

  NOTE: at the moment adhoc-api only supports openai agents for these two

I attempted to go through and update all the API specs to follow these changes. They appear to be working when I test them independently of Biome. The only one I'm not sure about if it's handled correctly is the src/biome/api_agent.yaml
