Mark transform as not-nullable

The ReadMe states

> Mark `Component.gameObject` and `Object.name` as not-nullable

But `transform` is not explicitly marked as not-null as well despite Unity official documentation stating

> Every GameObject has a Transform

**Source:** https://docs.unity3d.com/Manual/class-Transform.html

Is there a specific reason it isn't covered as well? Could this be fixed / added?\

**EDIT:** Both `Component.transform` and `GameObject.transform` are affected.
First one is accessed when just typing `transform` and second one when typing `gameObject.transform` explicitly.
