Describe the bug
Originally Described Here

When attempting to access the NvidiaRanker() model with model="nvidia/llama-3.2-nv-rerankqa-1b-v2", it returns ValueError: Model 'nvidia/llama-3.2-nv-rerankqa-1b-v2' is unknown. Please provide an api_url to access it. despite it existing in the Nvidia catalog.
Code:

alternative_ranker = NvidiaRanker(
    model="nvidia/llama-3.2-nv-rerankqa-1b-v2",
    api_key=Secret.from_env_var("NVIDIA_API_KEY")
)

Models nv-rerankqa-mistral-4b-v3 and llama-3.2-nv-rerankqa-1b-v1 are working as expected.

To Reproduce
Colab notebook for recreation.

Describe your environment (please complete the following information):

• OS: WSL Ubuntu 24.04.1 LTS on Windows 10 x86_64
• Haystack version: haystack==0.42

@julian-risch What do you think about adding the v1/retrieval/.../reranking url to

https://github.com/deepset-ai/haystack-core-integrations/blob/122a27b7885398b717fed01907193d5f658ccb36/integrations/nvidia/src/haystack_integrations/components/rankers/nvidia/ranker.py#L116C1-L116C73

and removing _MODEL_ENDPOINT_MAP, in case more ranking models will stored there?

[d-kleine]

I found another missing reranker model: https://build.nvidia.com/nvidia/rerank-qa-mistral-4b

"nv-rerank-qa-mistral-4b:1": "https://ai.api.nvidia.com/v1/retrieval/nvidia/reranking",

As you can see, the paths for the model and the URL are also different
