chore(scripts): Convenience script to update local generated artifacts (

#1349)

Adds a convenience script that updates all local generated artifacts.
Useful after pulling latest master on a working copy that's already set
up. When no changes are needed, it runs in about 10s (most of it being
recompiling noir contracts, since we are not detecting if rebuild is
needed or not for them), compared to a bootstrap.sh run that takes over
1min.
