fix: use T1 for sending chunk endorsements (#12632)

We missed that when refactoring chunk endorsement logic. The old
`ChunkEndorsement` message was removed in #12131, but we forgot to add
the new message introduced in #11091.
I've noticed that by looking at mainnet metrics where
`VersionedChunkEndorsement` message is only sent via T2.
