https://github.com/godotengine/godot/pull/92032 updated the logic to enable / disable the remote debug button, and in doing so added a `can_export` check.
However, no events / notifications are dispatched when the value of the `can_export` check changes, which in turn prevents the logic used to enable / disable the remote debug button from running again.
The fix consists then in removing the `can_export` check, so that the remote debug button shows as `enabled` when a preset is present and is runnable.
