Feature Request: Automatically Generate Accept Headers

[Daniel-Vetter-Coverwhale]

Description

It would be really awesome if ogen would automatically generate an Accept header parameter and enum options for it based on the content-types in the response for a given operation. That way we can avoid specifying an Accept header ourselves (which I think openapi doesn't want us to do) and we can automatically deal with new content types as they are added to the spec without having to manually keep the enum in the header parameter in sync.

          "200": {
            "description": "200 OK",
            "content": {
              "application/vnd.sambasafety.json;version=2.0.4": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrJson2_04Response"
                }
              },
              "application/vnd.sambasafety.json;version=3.0.0": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrJson3_00Response"
                }
              },
              "application/vnd.sambasafety.xml;version=2.0.0": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrXml2_00Response"
                }
              },
              "application/vnd.sambasafety.xml;version=2.0.2": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrXml2_02Response"
                }
              },
              "application/vnd.sambasafety.xml;version=2.0.3": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrXml2_03Response"
                }
              },
              "application/vnd.sambasafety.html": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrHtmlResponse"
                }
              },
              "application/vnd.sambasafety.pdf": {
                "schema": {
                  "$ref": "#/components/schemas/IntelligentMvrPdfResponse"
                }
              }
            }
