Note: Only replaced 2 instances to test, Node.get_children and TileMap.get_used_cells Note: Will do a mass replace on later PRs of whathever I can find, but probably need a tool to grep through doc. Warning: Mono will break, needs to be fixed (and so do TypeScript and NativeScript, need to ask respective maintainers)
