[SageMaker] New Flux.2 image generation example

[ehcalabres]

Description

This PR adds a new SageMaker example about image generation with the Hugging Face vLLM Omni DLC. The topic of the example is: Decorate your house with Flux.2 and Amazon SageMaker AI

It also adds a couple of improvements to the SageMaker docs:

• Adds the option to include the author and the last modification date for tutorials, as in our other cloud providers docs (i.e. GCP or Microsoft). It also allows to specify the author's Hub handle, and it will add a link to the Hub profile.
• Notebook assets are replaced by an URL to the respective asset in the huggingface/documentation-images dataset.

Note

Low Risk
Documentation and example-generation scripts only; no production application or auth logic changes.

Overview
Adds a new SageMaker SDK tutorial notebook that deploys FLUX.2-klein-4B on the vLLM-Omni DLC for room redesign (image editing and optional text-to-image), including endpoint setup, chat-completions routing via CustomAttributes, a Gradio interior studio, optional MCP, and cleanup.

Updates the SageMaker docs build so generated example pages show author (with HF profile links from notebook metadata) and last updated (from git history on the source notebook), and rewrites local ./assets / ./imgs image links to the huggingface/documentation-images dataset instead of raw GitHub paths in hub-docs.

hey @ehcalabres, this looks great 😄 I ran it end to end and confirm it's working correctly.

I just noticed that image_to_data_uri and resize_to_multiple_of_16 are defined/redefined in the Gradio cell,
