message: fix(CI): add npmrc config
diff: #
  -# NOTE: Currently `yarn install` does not correctly install all executables under
  -# `node_modules/.bin/`. NPM does seem to correctly do this. Once yarn is correctly installing all
  -# `.bin` items, this should be switched back to `yarn install`. The missing bin items break testing,
  -# scss linting, and docs generation (compodoc)
  -# Issue: https://github.com/yarnpkg/yarn/issues/760
  +# Authenticate NPM by adding our token
  +echo "//registry.npmjs.org/:_authToken=${NPM_TOKEN}" > ~/.npmrc
  +
  yarn install --frozen-lockfile
