Closing as the solution is to either:

• Use `hibernate.dialect` instead of `jakarta.persistence.database-product-name` when you need to use the minimum version
• Or set the version explicitly to `0` (though that will lead to warnings)

Thanks for the discussion as this allowed me to find a solution in Quarkus.
