Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.58.0-insider
• OS Version: Linux x64 5.10.41-1-MANJARO snap

Steps to Reproduce:

1. Open command palette (ctrl+shift+p)
2. See a command with a keybinding for a different OS than the one you're running, indicated next to the command name

If a keybinding is defined with different bindings per OS in the package.json, it seems that only the first one defined is shown to the user in the command palette, rather than showing the correct keybinding for the user's OS. This has caused confusion with an extension I maintain.

With the below keybinding defined in Calva's package.json, it seems only the "mac" shortcut is shown in the command palette, regardless of the user's OS.

{
    "command": "paredit.forwardSexp",
    "mac": "alt+right",
    "win": "ctrl+right",
    "linux": "ctrl+right",
    "when": "calva:keybindingsEnabled && editorLangId == clojure && editorTextFocus && paredit:keyMap =~ /original|strict/ && config.calva.paredit.hijackVSCodeDefaults && !calva:cursorInComment || calva:cursorAfterComment"
}
