[Feat] Allow setting supports_vision for Custom OpenAI endpoints + Added testing (#5821)

* add test for using images with custom openai endpoints

* run all otel tests

* update name of test

* add custom openai model to test config

* add test for setting supports_vision=True for model

* fix test guardrails aporia

* docs supports vison

* fix yaml

* fix yaml

* docs supports vision

* fix bedrock guardrail test

* fix cohere rerank test

* update model_group doc string

* add better prints on test
