Property 'headers' does not exist on type 'ServerResponse<IncomingMessage>'

Hi.

First of all, thanks for this awesome library.

While using it, I was dealing with an issue related to disabling headers on the logged messages and have stumbled up with this issue.

However, when implementing the afore mentioned example, I am getting the error:

Property 'headers' does not exist on type 'ServerResponse<IncomingMessage>'.

Here is my implementation:

export function createHttpLogger(logger: Logger): ReturnType<typeof pinoHttp> {
  return pinoHttp({
    logger,
    serializers: {
      req: pino.stdSerializers.wrapRequestSerializer((req) => {
        return {
          id: req.raw.id,
          method: req.raw.method,
          path: req.raw.url?.split('?')[0], // Remove query params which might be sensitive
          // Allowlist useful headers
          headers: {
            host: req.raw.headers.host,
            'user-agent': req.raw.headers['user-agent'],
            referer: req.raw.headers.referer,
          },
        };
      }),
      res: pino.stdSerializers.wrapResponseSerializer((res) => {
        return {
          statusCode: res.raw.statusCode,
          // Allowlist useful headers
          // TODO: open issue on Github to have this handled by pino-http
          headers: {
            'content-type': res.raw.headers['content-type'],
            'content-length': res.raw.headers['content-length'],
          },
        };
      }),
    },
  });
}

When I log the object res.raw.headers to the console I can clearly see that the property exists in the object.
Am I missing something?

If this is a problem, I would love to open a PR to have it fixed.

Thanks!
