Statistics screen uses wrong background textures

1.21.9 introduced a new statistics screen that looks like the “create new world” screen. The problem with this new screen is that it uses several incorrect textures when using a custom resource pack, or the built-in Programmer Art pack. It is inconsistent with the other options screens.

Observed/Expected results:

1. It uses “footer_separator.png”; it should use “inworld_footer_separator.png”

2. It uses “header_separator.png”; it should use “inworld_header_separator.png“

3. It should use “inworld_menu_list_background.png“ like the other options screens, but it does not.

4. The menu background texture covers up the “tab_selected.png“ and “tab_selected_highlighted.png“ textures; it should not cover them up. (This does not affect the built-in Programmer pack, but does affect custom packs that try to change the tab textures.)

5. The tabs don’t have “inworld” textures.

6. The tab header doesn’t have an “inworld” texture.

Attached screenshots show what it looks like in 1.21.8 vs 1.21.10, using the built-in Programmer Art pack. You can see the differences in the background and in the borders.
