refactor: use npm workspace instead of lerna (#281)

* refactor: use npm workspace instead of lerna

Lerna was deprecated a few months ago, and workspaces have gotten better.
Version bumping now goes through npm again, with a standard `npm version`
command. Usage is still the same as what's the in DAP contributing.md.

* add bump-version.sh helper

* make bump version better
