Slightly Improved Inference of Unnamed Tuples in JSON Formats

Slightly better inference of unnamed tupes in JSON formats. #57751 (Kruglov Pavel).
Improved inference of unnamed tuple types when reading JSON formats in ClickHouse.

Why it matters

This feature enhances the parsing of JSON data by better recognizing unnamed tuple structures without requiring explicit type definitions. It solves the problem of ambiguous or incomplete type inference for tuples in JSON formats, making data ingestion smoother and reducing the need for manual schema specification.

How to use it

Users benefit from this feature automatically when importing JSON data with unnamed tuples, as the improved inference is applied internally without requiring changes to existing queries or configurations.
