Update updater.sh

- by moving `cd "$ff_profile"` to the Execute section we don't need to restore working directory if we hit the Exit 0 in File Handling
- return 1 in confirmation() instead of exit and chained with `&& update_userjs` is functionally identical but always cleans up userjs_temps and restores the original working directory
