A lot of keys have no action set. In that case key.action is `undefined`, but the strict equality check of `action !== null` here will return true and we'll enter the if-case anyway. That's quite confusing and was not intended like that, so change the comparison to a less-strict operator. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/3286>
