Upgraded Neo4j driver and added support for Neo4j v5

[fabiomarini]

The Neo4j driver has been updated to v4 and the migration queries have been updated to add compatibility with Neo4j version 5.x that changed cypher syntax

I wanted to check in to see if this will be merged soon? I'm getting the following error when trying to run migrations

error: Server error: [Neo.ClientError.Statement.SyntaxError] Invalid constraint syntax, ON and ASSERT should not be used. Replace ON with FOR and ASSERT with REQUIRE. (line 1, column 1 (offset: 0))
"CREATE CONSTRAINT ON (a:SchemaMigration) ASSERT a.version IS UNIQUE"
