IN clause with list parameter broken in 4.0.4 (regression from 4.0.3) #738

Describe the bug

When using use_inline_params=True and passing a Python list as a parameter for an IN clause, the connector incorrectly renders it using ARRAY(...) syntax instead of a parenthesized tuple. This results in invalid SQL that Databricks rejects.

❗ This is a regression: the same code works correctly with version 4.0.3 and fails with 4.0.4.

To Reproduce

from databricks import sql
from databricks.sdk.core import Config, oauth_service_principal


query = """SELECT 'a' WHERE 'a' IN %(foo)s"""
parameters = {"foo": ["a", "b"]}

config = Config(
   host=f"https://{DATABRICKS_SERVER_HOSTNAME}",
   client_id=DATABRICKS_CLIENT_ID,
   client_secret=DATABRICKS_CLIENT_SECRET,
)

def credential_provider():
   return oauth_service_principal(config)

with sql.connect(
   server_hostname=DATABRICKS_SERVER_HOSTNAME,
   http_path=DATABRICKS_HTTP_PATH,
   credentials_provider=credential_provider,
   use_inline_params=True,
) as connection:
    with connection.cursor() as cursor:
        cursor.execute(
            operation=query,
            parameters=parameters,
        )
        return cursor.fetchall_arrow().to_pandas()

With this pyproject.toml

[project]
name = "minimal-sample"
version = "0.1.0"
requires-python = ">=3.13"
dependencies = [
    "databricks-sdk==0.91.0",
    "databricks-sql-connector[pyarrow]==4.0.4",
]

-> Expected behavior

The query should be rendered as:

SELECT 'a' WHERE 'a' IN ('a', 'b')

-> Actual behavior

The query is rendered as:

SELECT 'a' WHERE 'a' IN ARRAY('a','b')

Which causes an error because ARRAY(...) is not valid SQL syntax inside an IN clause.

databricks.sql.exc.ServerOperationError: 
[PARSE_SYNTAX_ERROR] Syntax error at or near 'IN'. SQLSTATE: 42601 (line 1, pos 21)

== SQL ==
SELECT 'a' WHERE 'a' IN ARRAY('a','b')
---------------------^^^

Note:
This works perfectly with the 4.0.3 version !!!!
