Chore: Automatically install example dependencies (#164)

Previously, CI was explicitly running the `install-examples` script as
its own step. This was also necessary but not documented locally, so
`git clone; npm install; npm test` would show a couple failures when the
examples inherited the wrong ESLint dependency. The examples'
dependencies should now be installed automatically when running `npm
install` locally without any arguments.

Originally reported in #163.
