[Deployment] Updated building assets in favor of Encore over Assetic

The deployment page isn't up-to-date since we're using Encore instead of Assetic. So in this PR I added a pre-deployment task referring to the explanation of deploying assets using Encore. I also removed the part about dumping the assets using Assetic. If someone could however take a look if I did the reference thing correct, that would be a great help. This PR would close #9887 and close #8094.
