Update localization strings in action classes

Refactor the `Label` and `Description` properties in the
`GroupAction`, `SortFilesAndFoldersTogetherAction`,
`SortFilesFirstAction`, and `SortFoldersFirstAction`
classes to utilize a new `Strings` resource class. This
improves maintainability and consistency of localization
across the application.
