docs: refresh README installation and resources (#38119)

Browse Source 
README installation examples now use `uv add` consistently, matching the
repo's `uv`-based Python workflow. The top-level README also gets a
cleaner quickstart and resource section with current links for docs,
community, learning, and contribution guidance.

## Changes
- Replaced `pip install` snippets with `uv add` across package quick
install docs, including the Hugging Face extras and
`sentence-transformers` upgrade examples.
- Updated the top-level quickstart to show only `uv add langchain` and
refreshed the example model to `openai:gpt-5.5`.
- Pointed the LangGraph orchestration link at the LangGraph GitHub
repository.
- Consolidated top-level documentation and additional-resource links
under a single `Resources` section covering docs, ecosystem overview,
API reference, discussions, Academy, contributing, and the Code of
Conduct.
- Added LangChain Academy and Code of Conduct links to package README
resource sections.
