UI extraction order fix (#9099)

# Objective

Fixes #9097

## Solution

Reorder the `ExtractSchedule` so that the `extract_text_uinodes` and
`extract_uinode_borders` systems are run after `extract_atlas_uinodes`.

## Changelog

`bevy_ui::render`:
* Added the `ExtractAtlasNode` variant to `RenderUiSystem`.
* Changed `ExtractSchedule` so that `extract_uinode_borders` and
`extract_text_uinodes` run after `extract_atlas_uinodes`.
