docs(examples): add missing step for building at repository root first (

originjs#583)

This adds a step to some of the example README files for installing
dependencies and building at the repository root first.

I was running into the same issue as originjs#513 because I was following the
instructions exactly, not realizing that I needed to first install
dependencies and build at the repository root.

Fixes originjs#513.

 This repository is to showcase examples of how Module Federation can be used in rollup.
 
 ## Running Demo
-First, `cd packages\examples\basic-host-remote`, then run `pnpm build` and `pnpm serve`. This will build and serve both `host` and `remote` on ports 5000, 5001 respectively.

-- REMOTE (rollup-remote): [localhost:5001](http://localhost:5001/)
