Lexical version: 0.40.0

Steps To Reproduce

0. OS: Windows 10 (22H2), Windows 11 (24H2), Ubuntu 22.04.5 LTS / Browser: Google Chrome 140.0.7339.127, Google Chrome 144.0.7559.133, Firefox Developer Edition 148.0b15
1. Set English and another keyboard layout in the OS (for example, English (US) and Russian (RU)).
2. Enter any text into the lexical input field so that a historyUndo action becomes available.
3. Press the keyboard shortcut (Ctrl+Z) to trigger the historyUndo native browser event.
4. Press the keyboard shortcut (Ctrl+Y or Ctrl+Shift+Z) to trigger the historyRedo native browser event.

The current behavior

• lexical.js does NOT trigger REDO_COMMAND because the native historyRedo event is not fired.
• lexical.js does NOT trigger REDO_COMMAND because the event.key equals to "я" not "z", but it is same physical key button in the keyboard.
• lexical.js detects keyboard shortcuts based on event.key instead of event.code (https://github.com/facebook/lexical/blob/main/packages/lexical/src/LexicalUtils.ts#L990).
• The browser menu is not aware of Lexical’s history stack and therefore disables the “Redo” option (I suspect there are browser restrictions).
• My screencast: https://github.com/user-attachments/assets/3e086e9d-95df-4940-84ec-ccb561a5d0bd

The expected behavior

• lexical.js should process REDO_COMMAND when Ctrl+Y or Ctrl+Shift+Z is pressed (with any non-English keyboard layout).
• lexical.js should determine all shortcuts using event.code by default (https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code#examples).

Impact of fix

• Affects all users who are not using an English keyboard layout.
