Allow better translations of '1 note deleted' browser tooltip

Currently it's hard to properly translate '1 note deleted' tooltip displayed when you use 'Delete' button in the card browser - the translation string ('%d note') lacks context you need to apply word inflexion.

I changed translating '%d note' to translating '%d note deleted', which is similar to an another translation string in [main.py](https://github.com/dae/anki/blob/591015417b6be67f535360496b7cdbc9abe74212/aqt/main.py#L1022).
