Remove type section output when dealing with objects

[andrewdelprete]

When an object is flow typed, a type heading AND a properties heading is rendered. The type section seems redundant and isn't formatted, whereas the properties section is. When dealing with large objects, the type section takes up a lot of space and isn't very legible.

Example:

export type MyType = {
  a: string,
  b: number,
  c: boolean
}

// output

## MyType

Type: {a: [string][3], b: [number][4], c: [boolean][5]}

### Properties

-   `a` **[string][3]** 
-   `b` **[number][4]** 
-   `c` **[boolean][5]** 

I think removing type in this case makes sense since properties is formatted and rendered better.
