Pull Request Overview
This PR adds support for serializing Boolean values by incorporating Bool type handling into the binary reader and updating the associated test and schema creation files.
- Added a new Boolean field with its getter/setter in SimplePOJO.
- Updated SQL queries and table creation SQL to include and utilize the new Bool type.
- Extended the binaryReaderMethodForType logic in SerializerUtils to support Bool serialization.

| File | Description |
|---|---|
| client-v2/src/test/java/com/clickhouse/client/query/SimplePOJO.java | Added a Boolean field "bool" with corresponding getter and setter methods, and updated toString() to include it. |
| client-v2/src/test/java/com/clickhouse/client/query/QueryTests.java | Modified the test query to select a Boolean constant and assert its value. |
| client-v2/src/test/java/com/clickhouse/client/query/QuerySamplePOJO.java | Updated the table creation SQL to use the Bool type instead of UInt8 for "bool" column. |
| client-v2/src/test/java/com/clickhouse/client/api/data_formats/internal/SerializerUtils.java | Added a new switch case to handle Bool type serialization by mapping it to readByte. |

- [nitpick] The new Bool case in binaryReaderMethodForType maps Bool to readByte and returns a byte descriptor, which may require implicit conversion to a Boolean. Consider using a dedicated boolean reader method if available or adding explicit conversion logic to improve clarity.
