Thanks for the PR. The test failure is due to our coverage ratchet. Because you improve the test coverage (yay!), you need to update the |

We simplify `GenericInputObjectFieldDefinitions` by using
tree-recursion, resulting in better error messages. Example
code to reproduce below, where the 'true' error is usage of
lists.
```hs
data family Test :: Nat -> Type
data instance Test 1 = Test
{ testField1 :: Int32
, testField2 :: Text
, testField3 :: Text
, testField4 :: [Int32]
} deriving (Show, Generic)
instance HasAnnotatedInputType Test
```
Before
```

:*: S1

• In the expression:
GraphQL.Internal.API.$dmgetAnnotatedInputType @(Test 1)
In an equation for ‘QL.getAnnotatedInputType’:
QL.getAnnotatedInputType
= GraphQL.Internal.API.$dmgetAnnotatedInputType @(Test 1)
In the instance declaration for ‘QL.HasAnnotatedInputType (Test 1)’
