`Cassandra 4.0rc1` moved protocol version 5 [out of beta](https://github.com/apache/cassandra/blob/trunk/CHANGES.txt#L52) but it is only
supported in `cassandra-driver >= 3.25.0`.
So ensure to explicitely set the maximum protocol version supported
by the driver to avoid errors when using `cassandra-driver < 3.25.0`
and `cassandra >= 4.0rc1`.
