[Elm] List in type alias has unnecessary parentheses

[andys8]

Description

A field in a type alias has always parentheses, which are not necessary.

type alias MyEntity =
    { id : Maybe Int
    , elements : (List Element)
    }

should be

type alias MyEntity =
    { id : Maybe Int
    , elements : List Element
    }

Swagger-codegen version

2.3.1

This is the line where the parentheses are hardcoded.
