AzureMLChatOnlineEndpoint - outdated endpoint_url validation

Checked other resources

[X] I added a very descriptive title to this issue.
[X] I searched the LangChain documentation with the integrated search.
[X] I used the GitHub search to find a similar question and didn't find it.
[X] I am sure that this is a bug in LangChain rather than my code.
[X] The bug is not resolved by updating to the latest stable version of LangChain (or the specific integration package).

Example Code

The following code:

chat = AzureMLChatOnlineEndpoint(
    endpoint_url="https://Mistral-large-2407-rag.swedencentral.models.ai.azure.com/chat/completions",
    endpoint_api_type=AzureMLEndpointApiType.serverless,
    endpoint_api_key="xxxxxxxxxxxxxxx"
)

ValidationError: 1 validation error for AzureMLChatOnlineEndpoint endpoint_api_type Endpoints of type serverless should follow the format https://<your-endpoint>.<your_region>.inference.ml.azure.com/v1/chat/completions or https://<your-endpoint>.<your_region>.inference.ml.azure.com/v1/chat/completions (type=value_error)

Description

Azure have updated their endpoint urls to exclude v1 from /v1/chat/completions.

The broken code is in (ln 457);

https://github.com/langchain-ai/langchain/blob/master/libs/community/langchain_community/llms/azureml_endpoint.py

        if field_value == AzureMLEndpointApiType.serverless and not (
            endpoint_url.endswith("/v1/completions")  # type: ignore[union-attr]
            or endpoint_url.endswith("/v1/chat/completions")  # type: ignore[union-attr]
        ):

Easy to fix by removing v1.
