Fix panic in gamepad_viewer example when gamepad is connected (#15854)

# Objective

Fixes #15832

## Solution

It seems that this was just a transliteration mistake during #15591.

Update the correct text span index.

## Testing

I tested on macos with:

`cargo run --example gamepad_viewer`
- without gamepad connected
- with gamepad connected
- disconnecting and reconnecting gamepad while running
