chore(npm): add ci-or-install script (#896)

* chore(npm): add ci-or-install script This adds a script which checks the npm version and runs either `npm ci` or `npm install` based on support. This is primarily to work around an issue where `npm install` modifies `package-lock.json` for newer npm versions. A side benefit is that `npm ci` is slightly faster than `npm install`. Fixes #893
