query_log table auto-recreation on manual deletion

Official CH changelog text
A query_log table is recreated on the fly if it was deleted manually (Kirill Shvakov).
The query_log table is automatically recreated if it is manually deleted.

Why it matters

This feature ensures that the query_log system table remains available even if it is accidentally or intentionally removed by users, improving system reliability and reducing manual recovery efforts.

How to use it

No specific user action is required. If the query_log table is deleted manually, ClickHouse will detect this and recreate the table automatically.
