Missing runtime hints for QueryDSL

[meistermeier]

Just noticed in combination with Spring GraphQL that there is at least one missing entry in https://github.com/spring-projects/spring-data-neo4j/blob/main/src/main/java/org/springframework/data/neo4j/aot/Neo4jRuntimeHints.java .
Namely QuerydslNeo4jPredicateExecutor.class.
While I am here I was thinking why we didn't include the reactive counterparts here(?)
Pulling in @mp911de / @christophstrobl to the discussion.

I assume that because of the evolutionary nature of native hints, we added hints for missing functionality that bubbled up as exceptions.

Please make sure to include hints for all imperative/reactive fragments and base repositories to be on the safe side.

@meistermeier you may draw some inspiration from here.
