Update clickhouse-benchmark to accept using - if

Updated clickhouse-benchmark to accept using - if in place of _ in its cli flags. #87251 (Ahmed Gouda).
The clickhouse-benchmark tool now accepts using - instead of _ in its CLI flags.

Why it matters

This feature improves usability and consistency by allowing users to use dashes (-) as separators in command-line flags for clickhouse-benchmark, matching common CLI flag conventions and reducing confusion or errors when specifying options.

How to use it

When running clickhouse-benchmark, users can specify CLI flags using dashes (-) instead of underscores (_). For example, both --max-queries and --max_queries are accepted.
