Set Application Category Type

[TheMoonThatRises]

This allows the user to set the category of the app by adding the key LSApplicationCategoryType to the Info.plist located in the application. This can be changed under Misc in the application's settings.

More specifically, this feature enables and closes #1085 "Game Mode", which can be accomplished by the user setting the application type to public.app-category.games for those on MacOS Sonoma.

This change is tested on MacOS Sonoma Developer Beta 23A5337a. This should not affect the changes, but should still be tested on a stable version of MacOS.

Other Notes for reviewers:

• Should LSApplicationCategoryType be localised? Currently, the code is implemented but was too time consuming to implement it in the localisation files.
• Should the installer popup be updated to a sheet or something similar to accommodate for the user to specify the application category type on installation? The setting has been implemented to set all the installing types to the specified value but per installation type setting would be require some major refactoring.
• Should the application inherent the application type from the IPA? Since the application's Info.plist does not initially have the key LSApplicationCategoryType, it would have to be located elsewhere as iOS apps still have the application category types. I will look into that but since it is not already implemented, I am not too sure it will work.

Just add it to the english loc file

This can be discussed later, as you said, it'll require a major refactor of installer code

This is worth to take a look since it should be provided with the app plist but we can implement it as nil meanwhile
