Description of change

Changing the default value for ssl_check_hostname to True, to ensure security validations are not skipped by default

[Copilot]

Pull Request Overview

This PR changes the default value for ssl_check_hostname from False to True to enforce stricter security validations by default. Key changes include updating the default in production code (in redis/connection.py, redis/client.py, and their asyncio equivalents) while tests and examples explicitly override the value for backward compatibility or simulation of insecure scenarios.

• Production connection and client constructors now default to ssl_check_hostname=True.
• Tests and examples explicitly pass ssl_check_hostname=False to simulate non-secure connections.
• Documentation examples have been updated to reflect the new production default.

• Changing the default to True enhances security by ensuring hostname validation; verify that any integrations or custom overrides still function as expected.
