[Security solution] Improve AI connector error handling

[stephmilovic]

Improves error handling on Generative AI connectors.

To test:

1. Save this file as *.ndjson
2. upload to saved objects page in Kibana
3. open ai assistant
4. use the connector selector to change between the new connectors and send a message to each one
5. confirm you get a descriptive error for the connectors labeled bad
