Support for OpenWebUI wrapped ollama

[lucascherzer]

OpenWebUI can expose its underlying ollama API: https://docs.openwebui.com/getting-started/api-endpoints/#-ollama-api-proxy-support

Technically, this would make it automatically compatible with Zed, but OpenWebUI may want to authenticate users.

By setting the Authorization Header, you can comply with this. If the zed config somehow supported this, OpenWebUI support could be tagged onto ollama support. Take this example request:

curl https://openwebui.local/ollama/api/generate -d '{
  "model": "llama3.2",
  "prompt": "Why is the sky blue?"
}'
-H "Authorization: Bearer $OPENWEBUI_API_KEY" 

The body in this case, is standard ollama stuff, only the header at the end has to be added for it to work.
