ScyllaDB 5.2 nodes are created out of compliance with docs

[lattwood]

Generally a "new default" is created by changing the default value used when decoding the config that is used in the absence of the value- not changing a config variable in a shipped configuration file.

This isn't an issue with this project but it's an issue with ScyllaDB's communication with downstream consumers/orchestrators, such as this ansible role.
