…etKD (#4064)

Since #3997 we use a dedicated
AlgorithmID for vetKD. However, the PR missed to use this algorithm ID
also in batch delivery, which led to the long running system test
`//rs/tests/consensus/vetkd:vetkd_key_life_cycle_test` getting broken
(see #4060). This PR fixes this by
using `AlgorithmID::VetKD` also in batch delivery.
