Motivation:
`HttpConversionUtil#toHttpResponse` translates `Http2Headers` to `HttpResponse`. It uses `#addHttp2ToHttpHeaders(..., boolean isRequest)` to do so. However, `isRequest` field is set to `true` instead of `false`. It should be set to `false` because we're doing conversion of Response not Request.
Modification:
Changed `true` to `false`.
Result:
Correctly translates `Http2Headers` to `HttpResponse`.
