Remove HTTP/2 response headers in Node.js with removeHeader()

Node.js's Http2ServerResponse.removeHeader() method removes a previously set response header before it is sent to the client, helping prevent unwanted headers from being included in an HTTP/2 response. The method takes a header name as its argument and returns undefined, working only before headers are sent. It allows developers to clean up or modify response headers, such as removing sensitive information or adjusting configuration based on request handling logic. Examples demonstrate removing headers like Content-Type or Foo from responses, with output showing the headers list updated accordingly. The method is useful for customizing final response headers and ensuring only necessary information reaches the client.
