fix(version): update package-lock at the root if it exists

[fahslaj]

Description

Updates the package-lock file in the root after running lerna version.

Motivation and Context

This removes the need to manually update the package lock file after a new version is tagged.

How Has This Been Tested?

I have tested this manually on the lerna repo itself. It is also covered by end to end tests.

This seems to remove all entries from the root package-lock.json that bootstrapping with hoisting adds to the file.
