Fixing build pipeline for 4.3.0
As I mentioned in release 4.3.0, it could go wrong and it did 🙈 The build was not triggered so there will be no 4.3.0 image.
I think that's fixed now. If so I'll just let there be a hole where 4.3.0 should have been. If not then I guess I have to clean up some tags 😅
