Description

When porting typescript-angular client to angular13, i noticed a support for a delete body parameters that did not match the angular doumentation. Indeed, it produces uncompilable code.

In the openapi v3 spec (https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#requestBodyObject), it is mentionned The requestBody is only supported in HTTP methods where the HTTP 1.1 specification RFC7231 has explicitly defined semantics for request bodies..
In RFC7231 (https://datatracker.ietf.org/doc/html/rfc7231#section-4.3.5), it is mentioned A payload within a DELETE request message has no defined semantics.
In the test petstore specification file, adding a request in a delete method produces an invalid spec rejected by the generators.
