fix(cli): remove unnecessary dom lib from default TypeScript config created with cdk init (#295)

Fixes #294

This change also removes `"dom"` from the `tsconfig.json` files of
additional packages that are all intended to run in a Node.js
environment, not in the browser.

Since these packages are not expected to use any web runtime-specific
APIs, removing `"dom"` helps prevent accidental use of browser-only
types across the codebase.
