[Fix] Swapped deprecated keyCode to key.

Summary:
Swapped keyCodes to keys and changed values accordingly. We shouldn't allow keyCode to be added to codebase anymore.
Fixing: https://linear.app/comm/issue/ENG-2212/keyboardeventkeycode-is-deprecated-we-should-use-key-instead

Test Plan:
Chat input - sends message on enter
Color picker - I think we're actually using ColorSelector and this file is not used anywhere,
shoudl I create issue to delete it?
Modal overlay - modals still close on escape,
Calendar entry - blurs on escape,
Multimedia overaly - closes on escape,
