Fix typo on declaration

[jgoux]

I just saw that this file was used by the VS Code purescript-language extension for the grammar.
Maybe this will fix the issue with record highlighting ?

This doesn't look wrong (other than the change is in a generated file), but won't fix your issue I think. This is the highlighting I see in atom:

And these are the scopes of "foo" in each case:

As you can see the newtype has a couple of "record" while the other doesn't. I guess all this is because Haskell records declarations give special meaning to the record fields, while really they are just any other type in PureScript. So Int -> { foo:: Int } should render the label the same.

newtype Foo = Foo
  { foo ∷ String
  , bar ∷ Array String
  }

type Foo =
  { foo ∷ String
  , bar ∷ Array String
  }

foo :: Int -> { foo :: String }

I think i propose highlighting records everywhere the way they now appear in the data/newtype declarations, starting looking at this.
