low_power example: pick nits (#12437)

Browse source 
# Objective

- no-longer-extant type `WinitConfig` referenced in comments
- `mouse_button_input` refers to `KeyCode` input
- "spacebar" flagged as a typo by RustRover IDE

## Solution

- replace `WinitConfig` with `WinitSettings` in comments
- rename `mouse_button_input` to just `button_input`
- change "spacebar" to "space bar"
