Switched to more correct JSDoc types for primitives (TryGhost#27430)

no ref

This is a types-only change that should have no user impact.

This is, effectively, the whole diff:

```diff
-@param {String} foo
+@param {string} foo
```

`String` is less correct than `string`, and [will not be supported by
TypeScript in an upcoming version][0].

All I did was run `sed` on a bunch of files.
