Fix gitignore pattern for vault related files
previous pattern ignored any file that started with 'vault_'.
While not affecting changes to the vault_key_manager.py file that was
already checked into the repository, this pattern effectively hides said
file from many modern search tools (like ack, ag or ripgrep)
that by default ignore files according to .gitignore patterns.
This patch changes this pattern to ignore 'vault_*' files and
directories only in the root of the repo.
