Downgrade to husky v4 (#456)

## Summary:
The prepare script added by husky causes yarn to be re-entrant in its installs, which can lead to the same tarball being unpacked more than once at the same time, corrupting itself

See yarnpkg/yarn#6312 and yarnpkg/yarn#2629


Issue: none

## Test plan:
`yarn test`

When we deploy to gcloud, it should deploy.
