fix: platform check on set_show_menu_on_left_click

[sandercox]

The platform check was broken after a merge I'm afraid. It needs to spell out target_os in the check.

This is regression caused by changes in #11726 compared to the changes merged from #11729.

windows is a shortcut for target_family = "windows" and should work. (there's another unix shortcut but that includes macos and linux so we don't use it often)

Right... I would swear I had issues that went away with changing this but changing it back now it's still all ok. Sorry for my lack of knowledge here.
