macOS: Remove multi-keystroke rendering in title of menu item (#26448)

Smit Barmase created 

Closes #25483

Currently, macOS doesn't support showing multi-keystroke shortcuts in
menu items. We can use an attributed string to differentiate them, but
that breaks consistency with traditional shortcuts.

This PR removes the hack of concatenating the multi-keystroke shortcut
to the title, as it looked a bit janky.

Release Notes:

- N/A
