Typescript client misses `body` argument in the POST/PUT/PATCH requests

Description

The generated typescript client does not use the body argument when calling http PUT, POST or PATCH.

return this.httpClient.put(
      `${this.basePath}/contacts/${encodeURIComponent(String(contactId))}`,
      {
        withCredentials: this.configuration.withCredentials,
        headers: headers,
        observe: observe,
        reportProgress: reportProgress
      }
);

Suggest a fix/enhancement

The client should use the body argument when calling http PUT, POST or PATCH.

return this.httpClient.put(
      `${this.basePath}/contacts/${encodeURIComponent(String(contactId))}`,
      body,
      {
        withCredentials: this.configuration.withCredentials,
        headers: headers,
        observe: observe,
        reportProgress: reportProgress
      }
);

Start with the generated contacts.services.ts file and the supplied OpenAPI declaration, then trace the TypeScript client generation entry point and its templates. Regenerate the client and verify that POST, PUT, and PATCH calls pass the body argument before the request options, using the shown output as the expected result.
