Support spring.data.neo4j.uri and authentication-related settings again #22653
Description
With #22299, Spring Data Neo4j no longer bootstraps the connection to the Neo4j server and the related properties have been flagged as "error" with a replacement to the raw drivers counterpart.
Rather than just doing it, it should be feasible to still read the spring.data.neo4j one and use them as a fallback if they are set. This should therefore move the deprecation level to warn and make the upgrade a bit more transparent for users.
