Fix broken "Go to Home View" shortcut on macOS

The previous shortcut CMD+OPT+H is already bound by the system (hide other
windows) and cannot be overridden. This commit changes the shortcut to
CTRL+SHIFT+H on macOS while keeping CTRL+ALT+H on other platforms.

Note that both CTRL+OPT+H (hide cursor) and CTRL+H (delete previous character)
are bound by the system as well and wouldn't have worked as a replacement.

Fixes: vector-im/element-web#16692
