fix: drop dead translate_number entry from card-type alist (upstream #43)

The card-type alist mapped translate_number to a function that no
longer exists in the file. Cards with DRILL_CARD_TYPE: translate_number
crashed with void-function during drill instead of being skipped.

Reporter (issue #43, 2021) said they had old decks using the
documented translate_number type and were getting the crash on
restore. The function was apparently removed at some point without
clearing the alist entry.

Removed the alist entry so entry-f's no-presentation-fn branch fires
and returns skip after messaging the user. Legacy decks now degrade
gracefully instead of crashing the session.

Tests in tests/test-org-drill-translate-number-regression.el lock the
behavior in (entry-f returns skip on translate_number, alist no
longer carries the entry).
