Fix dependencies in social_media.libraries.yml

We'll want the IIFE to take this form:

(function (Drupal) {
  ...
})(Drupal);

I think all that #2 needs is to pass the Drupal object from outer scope to the IIFE inner scope in this fashion and it should be good to go.

Thanks!

Updated patch #2 by addressing #9, please review it.

Thanks!

This is going to sound ironic, but I am actually not on any social media platforms!

I'm tagging this as needing manual testing. If the community can successfully perform an end-to-end test with the Facebook Send functionality with #10 applied and confirm here, I'll gladly merge it.

Thanks!
