George Kalpakas 4c5e085c93 build(docs-infra): update docs examples package.json templates wrt core-js (#36143)
The `core-js` dependency is no longer included in `package.json` for
`cli`-type examples, but only for the `systemjs` ones. This commit
updates the `package.json` templates to reflect that (and also updates
the `npm-packages` guide accordingly).
