Add example: deploy Faster-Whisper as a custom model on a SageMaker Triton MME

[eldadcohen1]

Adds an example showing how to deploy a pre-trained Faster-Whisper-Large-v3 model from Hugging Face as a custom model on an Amazon SageMaker multi-model endpoint (MME) backed by Triton, including building a custom Triton container and running audio-transcription inference.

Description of changes:

• New example under deploy_and_monitor/sm-triton_mme_faster_whisper/ (notebook, README.md, and a sample audio file), following the current repository structure and sm-triton_* naming convention.
• Registered the notebook in the Deploy and Monitor toctree in index.rst.
• CI badge URLs and kernelspec (conda_python3) match the sibling Triton examples.

This supersedes #4608 / #4887, which targeted the legacy main branch and the old sagemaker-triton/ layout. This PR targets the current default branch and the new folder structure.

Testing is done:
Tested on AWS SageMaker.

@mollyheamazon can you please review and approve

The notebook uses backend: "python" in config.pbtxt, but there's no cell that writes the required model.py into the model directory. Could you add the %%writefile cell for it? Without it a reader can't reproduce end-to-end.

Another note: This notebook uses raw boto3 calls rather than the SageMaker Python SDK. It might be a better fit for awsdocs/aws-doc-sdk-examples (which hosts boto3 examples)
