Summary of Changes

The CacheModel class in com_cache still uses some deprecated method to create cache controller. This PRs update code in that model to remove the usages of these deprecated code. I also simplied the code getCache method abit, reduce the options passed because they have same value with default cache options

Testing Instructions

• Use Joomla 6.2
• Go to System -> Global Configuration, System tab, set System Cache to one of the two ON options
• Access to frontend of your site, view an article for example to have cache generated
• Apply patch
• From administrator area of your site, access to System -> Maintenance -> Clear Cache, try to Delete, Delete All, Clear Expired Cache and make sure it is still working OK
