Undefined array key "content" (MS OpenAI Content Filtering issue)

When using using the Azure OpenAI API, if content filtering is kicked off an error is returned Undefined array key "content" as there is no content parameter in the array within CreateResponseMessage.php

    /**
     * @param  array{role: string, content: ?string, function_call: ?array{name: string, arguments: string}}  $attributes
     */
    public static function from(array $attributes): self
    {
        return new self(
            $attributes['role'],
            $attributes['content'],
            isset($attributes['function_call']) ? CreateResponseFunctionCall::from($attributes['function_call']) : null,
        );
    }

The choices array looks something like this,

    "choices": [
        {
            "index": 0,
            "finish_reason": "content_filter",
            "message": {
                "role": "assistant"
            },
            "content_filter_results": {
                "hate": {
                    "filtered": false,
                    "severity": "safe"
                },
                "self_harm": {
                    "filtered": false,
                    "severity": "safe"
                },
                "sexual": {
                    "filtered": true,
                    "severity": "medium"
                },
                "violence": {
                    "filtered": false,
                    "severity": "safe"
                }
            }
        }
    ],

That example above has the "sexual" filter triggered, hence why there is no content back from the assistant.

It would be great if this lib handled the content filtering issues (e.g. threw an exception with a message etc)
