Generate Generic type as parameter with <> instead of [ ]

[giancarlogamarra]

If my method on the server is using Generics then it is generated like this, which is great only for the '[' character it should be <>
//wrong
export interface Field [ HeaderField ] {
Name?: string;
Field?: __model.HeaderField;
}
//fine
export interface Field < HeaderField > {
Name?: string;
Field?: __model.HeaderField;
}
it would be great to have this tiny change.

Best regards
