spring-cloud-function-adapter-azure-web always returns 200

[cpiment]

Describe the bug
The Azure Web Adapter always returns response code 200, even if the method it calls from the Spring Web application returns any other response code.

Also I have detected that if you call a path that doesn't exist in the underlying Controllers, you also get a 200 response code and no errors in logs.

Sample

spring-cloud-function/spring-cloud-function-adapters/spring-cloud-function-adapter-azure-web/src/main/java/org/springframework/cloud/function/adapter/azure/web/AzureWebProxyInvoker.java

Line 130 in 118c223

Builder responseBuilder = request.createResponseBuilder(HttpStatus.OK);

Response code should be built using the response code from the underlying httpResponse, the same way the response body and response headers are generated.

Also I faced the same issue.
The response status should be 400.
