fix: show Ctrl instead of ⌘ on non-Mac keyboards in keyboard shortcut hints

The KeyboardShortcutHint component now detects the user's platform and
displays 'Ctrl' instead of '⌘' for Windows/Linux users. This fixes the
issue where the Reference Guide hint (and other keyboard shortcut hints)
incorrectly showed Mac-specific keyboard symbols on non-Mac platforms.
