commit 6925a9933a964e5d5e1f54c55a676f8604b2b8db
Author: Jacky Hu <jacky...@databricks.com>

    fix(csharp/test/Drivers/Databricks): Disable UseDescTableExtended by 
default (#3544)
    
    ## Motivation
    
    Disable `UseDescTableExtended` (use `DESC TABLE AS JOIN` to get
    metadata) by default in the Databricks Driver, so it will not call `DESC
    TABLE AS JSON` to get the meta data in Power BI by default. But customer
    can turn it on by setting `UseDescTableExtended=1` as the connection
    property in Power BI or setting
    `adbc.databricks.use_desc_table_extended=true` as ADBC connection
    properties.
    
    ## Change
    - Set `DatabricksConnection:_useDescTableExtended` default value as
    `false`
    
    ## Test
    - Unit test and E2E test
