Removal of deprecated SpecialPageFactory

[DannyS712]

Please note that the old SpecialPageFactory, deprecated in mediawiki 1.32, will likely be removed in 1.36. Its methods still have calls from this extension.

The replacement is to use MediaWikiServices::getInstance()->getSpecialPageFactory(), and use the new factory's methods. However, since this extension supports versions of MediaWiki that predate the addition of the new factory in 1.32, you will likely need to add conditional logic based on if the MediaWiki\SpecialPage\SpecialPageFactory class exists.
