D9 Replace deprecated File URL Method

Problem/Motivation

As per File Entity API:
https://api.drupal.org/api/drupal/core%21modules%21file%21src%21Entity%2...
File entities returning the URL to the physical file in File::url() is deprecated, use $file->createFileUrl() instead. See https://www.drupal.org/node/3019830

Proposed resolution
We will need to replace all:
$file->url();
to:
$file->createFileUrl()
