Careful to upgrade the ScyllaDB Docker Versions

[DanielHe4rt]

I was about to upgrade the versions from mostly examples to 6.0 but I remembered that there's two features that won't be working for now: LWT and CDC.

Tables in this keyspace will be replicated using tablets, and will not support the CDC feature (issue #16317) and LWT may suffer from issue #5251 more often. If you want to use CDC or LWT, please drop this keyspace and re-create it without tablets, by adding AND TABLETS = {'enabled': false} to the CREATE KEYSPACE statement.

It will be a small difference in how fast these constainers will start, so it's would be good to highlight it.
