Update the field widget after the Edit modal is closed

Looks great! Thank you for contributing to and using Entity browser.

With this patch, I get error when EB is used for field of media entity. When I try to add/edit media entity that uses field with EB, I get following error:
Uncaught TypeError: Cannot read property 'prototype' of undefined
for:
Drupal.AjaxCommands.prototype.entity_browser_value_updated = function (ajax, response, status) {

So possible solution is to add ajax dependency for: js/entity_browser.common.js, like I have provided in patch.
But in that case I'm not sure do we need defined dependencies in other parts of code:

1. src/Plugin/EntityBrowser/Display/Modal.php
2. src/Controllers/EntityBrowserController.php

I have attached zipped test module, so after it's installed just go to add media and error should be reproducible.

Committed. Thanks!
