docs(amazonq): update docs for connecting local language-server-runtimes (#7934)

## Problem
- `npm link` is not working for some people when connecting local
language-server-runtimes

## Solution
- `npm pack` has been working better for people, hence updating
documentation to include the `npm pack` approach
