Describe the bug

When setting wrapAsApiGateway to true, the host header is transformed to the HTTP/2 authority header.

Steps to reproduce the bug

1. VS

   virtualHost:
   domains:
   - '*'
   routes:
   - matchers:
     - exact: /
     options: {}
     routeAction:
       single:
         destinationSpec:
           aws:
             wrapAsApiGateway: true
             logicalName: hello
         upstream:
           name: aws-upstream
           namespace: gloo-system

2. US

   spec:
   aws:
   lambdaFunctions:
   - lambdaFunctionName: echo
     logicalName: echo
     qualifier: $LATEST
   - lambdaFunctionName: hello
     logicalName: hello
     qualifier: $LATEST
   region: us-east-2
   secretRef:
     name: aws-creds
     namespace: gloo-system

3. Lambda code to print request header to body for testing

   exports.handler = async (event) => {
   const response = {
       statusCode: 200,
       headers: {
           'Content-Type': 'application/json',
       },
       body: JSON.stringify({
           msg: "hello world",
           receivedHeaders: event.headers
       }),
   };
   return response;
   };

4. curl

   curl http://acf06d6774aef420b831b17d6e19c93f-1955450139.us-east-2.elb.amazonaws.com/ -H "Host: foo.bar" --http1.1    
   {"statusCode":200,"headers":{"Content-Type":"application/json"},"body":"{\"msg\":\"hello world\",\"receivedHeaders\":{\":authority\":\"foo.bar\",\":method\":\"GET\",\":path\":\"/\",\":scheme\":\"http\",\"accept\":\"*/*\",\"user-agent\":\"curl/7.87.0\",\"x-forwarded-proto\":\"http\",\"x-request-id\":\"851c635f-c471-48a1-8117-a49317c7ff33\"}}"}

Expected Behavior

Mirror what is produces by the AWS Application Gateway . Preserve the header host as host
