fix for passing query parameter to procedure search

[mocy]

Describe the changes you have made:

The query parameter was not passed properly to the open procedures search. It needs to be converted to a string to be properly URL encoded, and requests.get need to be called with params= (not json=)

I've debug and tested that it provide results that seem to make sense (eg. searching for email return related procedures. youtube seems to be returning relevant procedures). I'm unclear if passing the message in open_ai_messages is the best format to get results from this API end-point.

I wanted to keep the change to a minimum. But it might be nice to do better error handling here. It would be also really nice not to have to go to a remote server (but do the embedding search locally).
