AFAICS, the steps needed are:
- Update the docker images to install pnpm with curl https://pnpm.io/installation
- Update Quibble to use pnpm instead of npm
- Replace some commands like 'ci' and 'prune' with pnpm equivalents
- Make sure pnpm's cache is saved to a place that gets restored across jobs https://pnpm.io/continuous-integration
