Support TRUNCATE table without TABLE keyword

Why it matters

This feature simplifies the syntax for truncating tables by allowing users to omit the TABLE keyword, making the command more concise and aligned with SQL standards and user expectations.

How to use it

Users can now execute the command as follows without the TABLE keyword:

TRUNCATE table_name

or simply:

TRUNCATE table_name

(where table_name is the target table to be truncated).
