Fix validation of S3 request settings

Fix validation of S3 request settings. #76658 (Vitaly Baranov).
Fix validation of S3 request settings in ClickHouse to ensure correct and reliable configuration handling.

Why it matters

The feature addresses issues in the validation process of S3 request settings, preventing misconfigurations and potential errors when ClickHouse interacts with S3 storage. This improves stability and reliability for users leveraging S3 for data storage and retrieval.

How to use it

Users do not need to take special action to enable this fix; it improves the existing validation logic automatically. When configuring S3 request parameters in ClickHouse, the settings will now be properly validated during setup.
