fix: move client instantiation in AssistantsGetAssistantName and AssistantsListAssistants to inner function (#3043)

The OpenAI client instantiation was removed from the `AssistantsGetAssistantName` and `AssistantsListAssistants` components. This commit fixes the issue by adding back the OpenAI client instantiation in the `process_inputs` method of both components.
