Inform to expose routes annotation before run dump

[ismail1432]

Maybe I'm wrong but Using Webpack Encore I was trying to use FOSJsRoutingBundle for the first time. After runned dump command I don't have any routes in fos_js_routes.json , I had to expose them in annotations and run again the command. So we can inform people and put a link to the expose route part
