[darwin] Fix undo/redo

[stffabi]

I could only test it on the following config since I have no mac available with an older XCode or OS.

OS           | MacOS
Version      | 13.2.1
ID           | 22D68
Xcode command line tools  | N/A          | Installed | 2396
*Xcode                    | N/A          | Installed | 14.2 (14C18)

Fixes #2356

It's likely this will break in older macOS releases. I have a way to test this. I don't suppose you have a snippet you used for testing it do you? No worries if not possible 👍

Yeah also thought so, but really have no way to test this. Thanks for doing that.

I've just used a Wails vanilla project, added some text into the "greet" input box and hit cmd-z.

Wow, I'm not even sure how undo: wasn't there in the first place! undo: has been there since v10 so we're good! Thanks for this @stffabi !!!
