Update type of shotgun response

[Euen]

Change

-type headers()    :: #{} | proplists:proplist().
-type response() :: #{ status_code => integer()
                     , header => map()
                     , body => binary()
                     }.

to

-type headers()    :: #{} | proplists:proplist().
-type response() :: #{ status_code => integer()
                     , headers => headers()
                     , body => binary()
                     }.

Can this please be corrected to the headers type?
Now we have problems passing dialyzer tests.
