adapt webkpack patch for 8.23.1

we have to remove the (unnecessary) polyfill plugin, because some
transitive dependency (nodelib/fs.scandir) tries to access node specific
information that is stripped with these (browser targeting) polyfills

it's not necessary as we're targeting node anyway

also update the patch message to reflect the actual changes
