chore: migrate from yarn to npm (#757)

Keep packages up-to-date.

- use dependabot to keep track of updates and easily apply them
- remove zero-install committed package zip files (as this does not work with dependabot, or even renovate)
- use npm instead of yarn as a more common default choice (as this works just as well if we don't have zero install)
