Update GlobalTransform on insertion (#9081)

# Objective

`GlobalTransform` after insertion will be updated only on `Transform` or
hierarchy change.

Fixes #9075

## Solution

Update `GlobalTransform` after insertion too.

---

## Changelog

- `GlobalTransform` is now updated not only on `Transform` or hierarchy
change, but also on insertion.
