Description

  await app.register(swagger, {
    mode: 'dynamic',
    openapi: config.get('openapi'),
    exposeHeadRoutes: false
  })

Even if exposeHeadRoutes is set to false, HEAD routes still exist in the specification.

I traced the code and found that it works correctly after modifying the following code in addHook() (lib/util/add-hook.js):

    // routes.push(routeOptions)
    routes.push({...routeOptions})

I'm not sure if there is a problem with modifying it like this, or if there is another better way?
