fix: Correct ScyllaDB host required status and ssl default

- scylladb_host and scylladb_hosts are alternatives — either must be
  provided, not just scylladb_host. Changed both to Yes* with
  clarifying descriptions.
- scylladb_ssl default changed from `false` to `-` since the parameter
  is accepted but has no effect (not wired up in the connector).
  Documenting a default for an unused parameter is misleading.
