Add description for the new translation

As we localize the wipe data menu under the recovery mode, some
additional strings need the new translation. The strings include
1. The menu header that prompts a data wipe
2. Try again description
3. Factory reset description
4. The menu header to confirm a data wipe
5. Cancel description

We will resue the "Factory reset description" in the confirmation menu;
and the image_generator tool will be moved to this directory in later
cls.
