Verifing default keybindings wrapper fails

[tshino]

This is the cause of the failure in CI.

It seems verify_wrapper.js fails if some specific platform contexts, like isLinux, are contained in the default keybindings. And that condition meets for VS Code 1.87.0.

Following lines appears in the default keybindings for VS Code 1.87.0 for Linux and Windows.

{ "key": "ctrl+up",               "command": "chat.action.focus",
                                     "when": "inChatInput && isLinux || inChatInput && isWindows" },

This is redundant and unexpected for the script, but it is still valid and the script should not fail.
