Docs: TRUNCATE seems affected by keyword `SYNC` but it is not explicit in documentation

[LPauzies]

Describe the issue

In ClickHouse documentation, for TRUNCATE TABLE : https://clickhouse.com/docs/sql-reference/statements/truncate#truncate-table, the SYNC keyword seems not available. However, it is possible to perform such a query in a cluster 2S2R on a ReplicatedReplacingMergeTree table:

TRUNCATE TABLE db.table SYNC;

And it seems to TRUNCATE the table in all the replicas synchronously.

Is it possible to make it explicit in the documentation ?

Here is the original issue that create the investigations around "synchronous truncate" in our company : #3816
