Contributions summary:Guanhua's contributions primarily focused on updating and refining documentation within the Kyuubi project. They added documentation for the Flink Table Store connector, and subsequently, renamed this connector to Apache Paimon (Incubating) across various documentation sections, including those related to Spark SQL, Trino, Hive, and Flink SQL query engines.
