chore: Add install guide

[dagardner-nv]

Overview

• Document installing Fabric from source and packages
• Once Fabric is deployed on pypi the Package installation method will be listed first
• Minor cleanup to docs/getting-started/overview.mdx

Where should the reviewer start?

• I confirm this contribution is my own work, or I have the right to submit it under this project's license.

• I searched existing issues and open pull requests, and this does not duplicate existing work.

Summary by CodeRabbit

• Documentation
  • Added a new “Install” guide for NeMo Fabric, including prerequisites and multiple setup options (source build and package/wheel-based installation), plus example commands for installing runtime adapters.
  • Updated the quick start to make adding Cargo’s binary directory to PATH an explicit standalone step.
  • Extended the Getting Started navigation to include the new Install page and linked it from the docs index.

In `@docs/getting-started/install.mdx`:
- Around line 45-80: The install examples in the Fabric runtime and adapter
sections should explicitly target the active virtual environment rather than
relying on whatever interpreter uv picks up. Update the `uv pip install`
examples near the `just wheels` and `nemo-fabric[runtime]` /
`nemo-fabric[adapters-hermes-sdk]` commands to either include a venv activation
note or pass an explicit `--python` value so installs go into the intended
environment.
