`gamepad_viewer` example broken when a controller is connected

[NiseVoid]

Bevy version

11d1ebeed

Relevant system information

• Running Linux, happens on both wayland and X11 (trough xwayland).

What you did

With a controller connected run:

cargo run --example gamepad_viewer

When no controller is connected it starts correctly. When multiple controllers are detected it also crashes.

What went wrong

The app immediately exited

Figuring out when this happened would be nice, but I'm strongly guessing #12770 is responsible.

Pretty sure this is just a mistake migrating the example for the text rework, but I don't have a gamepad to test just this moment.
