[ML] AI Connector/Inference endpoints creation UI: Adds icon for AI21 labs and Llama Stack

[KodeRad]

Summary

Fixes #230463

The corresponding back-end pull request has not been merged yet to avoid showing AI21 Labs and Llama Stack providers without icons in the list of available connector services. This PR is intended to go first for that reason. Once we receive the updated list of services, the front end will be ready to display them correctly.

I’ve been provided with the expected response objects:
