Update localization for Git action classes

Refactor the `Label` and `Description` properties in
`GitFetchAction`, `GitInitAction`, `GitPullAction`,
`GitPushAction`, and `GitSyncAction` to utilize a new
`Strings` resource. This change improves the
maintainability and consistency of localization across
the application.
