Doc: Improve logical replication failover documentation.

Clarified that the failover steps apply to a specific PostgreSQL subscriber
and added guidance for verifying replication slot synchronization during
planned failover. Additionally, corrected the standby query to avoid false
positives by checking invalidation_reason IS NULL instead of conflicting.
