Thanks @szczys! Can we also update workflows to use npm ci rather than npm install to ensure we are installing the exact dependencies specified in our lockfile (example:

docs/.github/workflows/firebase-hosting-merge-develop.yml

Line 18 in a2eab1f

run: npm install && npm run build:dev

)

Good guidance, thanks! I also took this opportunity to:

• Update all github actions and pin them using a hash instead of a version
• Update to the most recent npm LTS
