Add a Redis ADBC guide explaining how to install and explicitly use the community-maintained RedisAdbcHook inside a Python task. Document connection extras, native library discovery, worker setup, and the driver's autocommit and write limitations.

Link the guide from the Arrow provider index and place a note beside the generic AdbcHook usage example. Use a guide-specific reference label because the external hook is not a registered Airflow connection type. Clarify that the Redis ADBC driver supports autocommit only and fix the section heading underline.

The guide distinguishes the external hook from Apache's Redis command provider and the generic Arrow hook selected by SQLExecuteQueryOperator. No provider registration or dependency changes are included.

Validation:

• Fast and manual prek checks passed.
• The connection documentation label validator passed.
• git diff --check passed.
• breeze build-docs apache.arrow common.sql was attempted but could not reach Sphinx: the CI Docker image build failed when dhi.io returned HTTP 403 for OS packages.

Historical Airflow 3.3.2 and Arrow provider 0.1.1 hook validation is linked in the guide. This documentation change does not alter runtime behavior.

A good addition to the docs but it needs some adjustments before merge.
