[Typescript-Anuglar] responseType not set on string response

Description

If response is a string, i get the following error when consuming the generated service:

Http failure during parsing for {API_URL}

Generated service:

return this.httpClient.get<string>(`${this.basePath}/accounts/${encodeURIComponent(String(accountName))}/account_name`,
            {
                withCredentials: this.configuration.withCredentials,
                headers: headers,
                observe: observe,
                reportProgress: reportProgress
            }
        );

If i add the line responseType: 'text' as 'json' to the options, everything works as expected.

}
}

Start in the TypeScript-Angular generator templates and reproduce the issue with the provided response schema. Verify that a generated service for a string response sets the HTTP response type to text and that the resulting request no longer fails during parsing.
