Bug 34943: (QA follow-up) Use `before_biblio_action` and an `action` param

This patch harmonizes the hook name and parameters with the rest of the
codebase.

To test:
1. Apply this patch
2. Run:
   $ ktd --shell
  k$ qa
=> SUCCESS: All looks green, and tests still pass (i.e. they were
correctly adjusted to the new schema).
3. Sign off :-D
