Add Apache Kyuubi Provider

[MonsterChenzhuo]

Description

This PR introduces a new provider for Apache Kyuubi.

Kyuubi is a distributed and multi-tenant gateway to provide serverless SQL on Lakehouses. It is compatible with the HiveServer2 protocol.

While the Hive provider can be used to connect to Kyuubi, Kyuubi often uses its own beeline executable or requires specific configurations. This provider adds a dedicated KyuubiHook and KyuubiOperator to streamline the integration and allow users to configure the specific path to the Kyuubi Beeline executable via the UI.

Changes

Added apache-airflow-providers-apache-kyuubi provider structure.
Implemented KyuubiHook (inherits from HiveCliHook):

• Adds a custom connection form widget beeline_path.
• Overrides command preparation to use the custom Beeline path if configured.
• Implemented KyuubiOperator (inherits from HiveOperator).
• Added Unit Tests for Hook and Operator.
• Added Documentation (Connection, Operator, Index).
