Obsolete the settings allow_experimental_variant, allow_experimental_dynamic, and allow_experimental_json by enabling all three related types unconditionally in ClickHouse.
Why it matters
This change simplifies the configuration by removing the need to enable experimental types via specific settings, ensuring that variant, dynamic, and JSON types are available by default for all users without extra configuration.How to use it
There is no longer a need to set allow_experimental_variant, allow_experimental_dynamic, or allow_experimental_json. The related types are enabled unconditionally, so users can directly use them without any additional settings.
