DATAGRAPH-1408 - Upgrade to Neo4j-Java-Driver 4.1.1.

From Spring Boot 2.4 onwards on, SDN will be the leading figure in regards of the driver version being used. For the release, we should bring Boot and SDN 6 to the same Java Driver.

The 4.x line will be API compatible and can always serve as a drop-in replacement for users.

Users can adapt their version in a Spring Boot project by setting `neo4j-java-driver.version`.

The Neo4j drivers of the 4.x line officially supports current and one previous version of Neo4j.
For example Driver version 4.1.x will support Neo4j 4.1.x and 4.0.x, driver version 4.0.x will support Neo4j 4.0.x and 3.5.x.
