Remove unused error texts

Those were copied from dhall-haskell back before I (Nadrieril) forked
dhall-rust from Nanotech. They have never been used.

-Explanation: Every optional element ends with a type annotation for the element
-that might be present, like this:
-
-
-    ┌────────────────────────┐
-    │ [1] : Optional Integer │  An optional element that's present
-    └────────────────────────┘
-                     ⇧
-                     The type of the ❰Optional❱ element, which is an ❰Integer❱
-
-
-    ┌────────────────────────┐
-    │ [] : Optional Integer  │  An optional element that's absent
-    └────────────────────────┘
-                    ⇧
-                    You still specify the type even when the element is absent
-
-
-The element type must be a type and not something else.  For example, the
-following element types are $_NOT valid:
-
-
-    ┌──────────────────┐
-    │ ... : Optional 1 │
-    └──────────────────┘
-                     ⇧
-                     This is an ❰Integer❱ and not a ❰Type❱
-
-
-    ┌─────────────────────┐
-    │ ... : Optional Type │
-    └─────────────────────┘
-                     ⇧
-                     This is a ❰Kind❱ and not a ❰Type❱
-
-
-Even if the element is absent you still must specify a valid type
-
-You declared that the ❰Optional❱ element should have type:
-
-↳ $txt0
-
-... which is not a ❰Type❱
-
