Use the new vector index creation syntax for Neo4j.

Browse Source 
To make the Neo4j module more future-proof, this commit
replaces the old vector index creation syntax with the new style.
Also, the new pattern is in line with the standard Neo4j index creation
and supports the _IF NOT EXISTS_ clause to run idempotent.
This allows us to remove the preceding call to check if the index exists.

As a consequent, the module will require Neo4j to be at least on version 5.15.
