documentation: add SDK cheat sheet

[jamilahmadzai]

Issue #, if available:

Closes #1255

Description of changes:

• Add a GitHub Pages-ready Amazon Braket SDK cheat sheet built from ordered Jekyll sections.
• Update the SDK snippets and include program sets, emulators, experimental capabilities, reservations, and hybrid job decorator usage.
• Add contributor instructions plus a generator for the plain Markdown companion file.

Testing done:

• python3 doc/cheat_sheet/_scripts/generate_markdown.py
• python3 -m compileall doc/cheat_sheet/_scripts/generate_markdown.py
• Verified doc/genai_cheat_sheet.md matches the generator output.
• Verified every ordered block in doc/cheat_sheet/_data/blocks.yml has a matching English include.
• git diff --check
• .venv/bin/tox -e docs
• .venv/bin/tox -e linters_check

unitaryHACK26:

I used GPT-5 Codex to help draft and check the documentation structure and snippets, then manually verified them against the current SDK source/examples and ran the checks above.
