"Loading env from encrypted .env.vault" message missing

The "Loading env from encrypted .env.vault file" info message is missing.

Went missing here: https://github.com/dotenv-org/python-dotenv-vault/commit/f5d23bf053d9f19e01316e78616dae51f4053d8a#diff-b0a4563233b30c2906cd1576ed02f90e736dbfff74592d5b2b669a68f6d61b25L29

Add back in.

Info log should be: `Loading env from encrypted .env.vault`
