[Elixir] fix ":body" handling (#1504)

* Fix swagger-api/swagger-codegen/issues/8138 swagger-api/swagger-codegen#8138

When JSON payload needs to be in the body (`"in": "body"`), it must not generate a multi-part body, but embed directly in HTTP body.

* update elixir samples

* update elixir client samples

* remove double quote
