Keyboard Shortcuts don't work on non-english (non-latin) keyboard layouts

### Prerequisites

- [x] I am running the latest version of ComfyUI
- [x] I have searched existing issues to make sure this isn't a duplicate
- [x] I have tested with all custom nodes disabled ([see how](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled))

### What happened?

Keyboard Shortcuts don't work on non-english (non-latin) keyboard layouts. `r` - no reaction, `ctrl+s` - html saving prompt. Etc

It's needed to use `event.code === "KeyR"` insted of `event.key === "r"`. I tested it on [this playground](https://developer.mozilla.org/en-US/play?uuid=a529d57d-574a-4d7a-99ad-39d4423e9b8e&state=VVLBjpswEP2VkdsqRCLsVlUPZZNI7WqlrdpDD3vksAYPwY2xkT2QRCn%2F3jHQjXpj5r15b%2FyGq2ioNSIX225fWIBfHkOAI14COAvUYPwunfQKyEFAhFMjaQJ%2BLMDTgJZW0xBIq6ByCmGQpscQFaVHqJ0HlFXDmpgVdnsXzbZKD6DVrhCup66nQgDJUluFZ%2B7dF2K%2FvWMKM0UqqhB4yXczE65RuHaWNrVstbnk8NVraVJ4RjMg6UqmEKQNm4Be1w%2BRXTqv0OfwsTtDcEYrKI2sjhN20oqaHL58%2FjCVrfQHbXOQPTlujIVdfPPaVX3YDDro0uC8BSNGW8zh05uwcuqAvuQA5mle%2F3fc%2FsRvc6dMqjmynzoQWvRJlCkEx8eoLUQa6wQjZQ27%2FWwDHKsNBB3sWL%2FqW0azyqMkfDIYq6QQXSHWDzO7ywjP9MgRMcQzr%2F9dK4%2FH2q3eXyeXjItxBX%2Bmy926sRpXr4vgm%2BkBaXH8dvmuktv11pnsOrTqsdFGJd2%2FTZZXh8o7Y15ccp%2FetEqnLgvyjPrQ0Dw0ThGQ75E%2FYosT5D%2BuRQ5RSX8U418%3D&srcPrefix=%2Fen-US%2Fdocs%2FWeb%2FAPI%2FKeyboardEvent%2Fcode%2F)
