Bump the version in the root package.json only. Do not bump the
version fields in the workspace packages (packages/quicktype-core,
packages/quicktype-graphql-input, packages/quicktype-typescript-input,
packages/quicktype-vscode) — those are intentionally left at their older,
independent numbers.
At publish time script/publish.sh runs npm version $VERSION --workspaces --force to sync the workspaces up to the root version. npm version errors
with "Version not changed" (even with --force) if a workspace already
equals the target, so pre-bumping the workspaces in lockstep with root breaks
the release publish. Leave the workspaces stale and let the publish script
sync them.
