fix: npm run test required depdendencies (#6)

The depdendencies for the playground in `examples/playground/node_modules`
have to be installed for the tests to run successfully, since eslint
runs for both projects in one go.

This patch adds a pretest hook to make sure the depdendencies are
installed before running the tests.
