Fix maven dependencies (#266)

`com.datastax.oss:java-driver-parent:pom` is not meant to be pulled as a dependency
(see https://docs.datastax.com/en/developer/java-driver/4.17/#getting-the-driver)

However, `com.datastax.oss:java-driver-core:jar`, `com.datastax.oss:java-driver-query-builder:jar`, `com.datastax.oss:java-driver-mapper-runtime:jar` are.

`liquibase-cassandra` only uses the first one of those three, and it's already pulled as a transitive dependency of `com.ing.data:cassandra-jdbc-wrapper:jar`, so no need to repeat it in liquibase-cassandra's pom neither.
