Improve URL Handling for Form Submissions with Excluded Query Parameters

Problem/Motivation

• The original implementation of Drupal.Ajax.prototype.beforeSerialize only handled click events on links ( elements), ignoring AJAX-enabled form submissions, which led to incomplete or incorrect URL updates for exposed filters.

Proposed resolution

• Updates Drupal.Ajax.prototype.beforeSerialize to handle AJAX-enabled form submissions by processing serialized form data (element.serialize()) instead of only handling links ( elements).

• Introduces an updatedUrl property in the options object to allow URL modifications in beforeSerialize and reuse it in beforeSubmit.

• Ensures that both link clicks and form submissions are handled consistently, providing improved compatibility with drupalSettings.viewsAjaxHistory.excludeArgs.
