docs: align adapter contract package readmes

[AjayThorve]

Overview

Align the adapter-contract package README titles and add the missing repository-facing README for the Python package.

Details

• add adapter-contract/python/README.md with package content from pypi.md, excluding PyPI-only badges and the hero image;
• use the shared NVIDIA NeMo Fabric Adapter Contract title in the TypeScript package README.

This is documentation-only and does not change package metadata or runtime behavior.

Validation

• /Users/athorve/Dev/mdemoret-team/nemo-fabric/.venv/bin/pre-commit run --files adapter-contract/python/README.md adapter-contract/typescript/README.md
• sed 8,13d adapter-contract/python/pypi.md | cmp - adapter-contract/python/README.md
• git diff --check

just docs was not run because no Fern docs or generated API references changed.

Where should the reviewer start?

Start with adapter-contract/python/README.md, then confirm the shared title in adapter-contract/typescript/README.md.
