This PR upgrades uuid into its latest version `9.0.0`. The previous default used version `v4` was kept where it was previously used and places using `v1` or `v5` are still using it. In this latest version they removed the deep import feature and as we are not using tree shaking it increased our bundles by a significant size. As such, I've moved this dependency into the `ui-shared-deps-npm` bundle. Co-authored-by: kibanamachine <42973632+kibanamachine@users.noreply.github.com>
