Reconstruct strings for Reviewer-actions' feedback

Reconstruct the strings for the feedback-toast message to Reviewer actions

Basically, use strings on Anki Desktop instead of the current ones. Create new ones as needed.
For Bury and Suspend, I set the style described in the following comment as a goal:
  #12446 (comment)

------------------------------

- Replace `<string name="buried_card">Card buried</string>`
        with `<string name="card_buried">Card buried.</string>`

- Remove `<string name="buried_note">Note buried</string>`
   (Instead of the string, its counterpart on Anki Desktop will work on the toast.)

- Remove `<string name="deleted_note">Note deleted</string>`
   (Instead of the string, its counterpart on Anki Desktop will work on the toast.)

- Remove `<string name="suspended_card">Card suspended</string>`
   (Instead of the string, its counterpart on Anki Desktop will work on the toast.)

- Replace `<string name="suspended_note">Note suspended</string>`
        with the following code:
                `<plurals name="note_suspended"
                        <item quantity="one">%d card suspended.</item>
                        <item quantity="other">%d cards suspended.</item>
                 </plurals>`
