Summary of Changes

The SiteApplication, AdministratorApplication, and ApiApplication all called $this->loadDocument() without passing $document argument, causing an internal fallback to the deprecated method Factory::getDocument() call.

This PR introduces createDocument() method on CMSApplication to create document object which bring the following improvements:

• Use dependencies (language, document factory) which are necessary to create document directly from the application rather than the static Factory.
• Avoid calling deprecated method Factory::getDocument() which was planned to remove in Joomla 7
• Consistent with how language is created and injected into application

Testing Instructions

• Use Joomla 6.2 (Joomla 6.1 is also OK)
• Apply patch, and access to random pages from frontend and backend of your site. If you are familiar with web services, try to execute a request with web service, too

Actual result BEFORE applying this Pull Request
