Subject: [PATCH] Update version format for usage with semver

Tracking the version under one `-prerelease` channel allows other packages to depend on `^0.1.0-prerelease` for the most up to date version.

Track the git sha for the release in package.json

Reuse the json package needed for writing the sha to retrieve the package.json version field
