Speedy installs

npm ci removes node_modules before it installs dependencies.
This means that caching them for the install step is useless.
If instead ~/.npm get's cached, npm ci will fly and it shaved off 10s of the CI build in this pretty small repo.
node_modules caching is still required for all following jobs after install.
