Hitting "R" with caps lock on doesn't reboot the cartridge
https://github.com/aduros/wasm4/blob/2c8c0127eb03dd690dae20a2187a0124b1358318/runtimes/web/src/index.js#L193-L196

Here, the hotkey is set as a lowercase "r", this causes that hitting it while the caps lock key is on, JS registers it as "R", thus the cartridge doesn't reboot.
