Cypher25 APOC proc func migration

[gem-neo4j]

Migrating procedures to APOC for next major (from APOC core).

Note: This also

• Fixes the build, so it works with latest unpublished Neo
• Updates gradle
• Fixes the kotlin
• Updates some dependencies including testContainers which was the timeout bug

There is another PR to come with docs for this, but that one can't be merged until we get a new branch etc next year
