refactor: 💡 type section is redundant and not formatted

When an object is flow typed, a `type` AND `properties` section is
rendered. The type section seems redundant and isn't formatted, whereas
the properties section is. This PR removes the `type` section when
dealing with an object type.

✅ Closes: #1326
