Feature: LLMS and Content Updates

[mbenavidez-amd]

Motivation

This pull request modernizes and simplifies the documentation build system, focusing on updating Python and Sphinx dependencies, removing custom code for LLMS text generation, and streamlining documentation references. The changes ensure compatibility with newer tools, delegate more functionality to upstream packages, and clarify documentation navigation.

Technical Details

Dependency and build environment updates:

• Upgraded the documentation build environment to Python 3.12 in .readthedocs.yaml for improved compatibility and future-proofing.
• Updated all Sphinx and Python package dependencies, including switching to rocm-docs-core[llms]==1.38.0 and updating many related packages to their latest versions in docs/sphinx/requirements.in and docs/sphinx/requirements.txt. [1] [2] [3] [4] [5] [6]

LLMS text generation simplification:

• Removed the custom LLMS text generation logic from docs/conf.py and enabled the standard rocm_docs_core LLMS text generation by setting rocm_docs_generate_llms = True.
• Deleted the manually maintained docs/llms.txt file, as it is now auto-generated.

Documentation content and navigation:

• Simplified the MI355X GPU validation documentation by replacing the detailed test tables with a reference to the consolidated Testing Overview, improving maintainability and clarity.

Minor code cleanup:

• Removed an unused import (Path) from docs/conf.py.

Test Plan

Confirm successful documentation build in ReadTheDocs.

Test Result

Build successful.
