Upgrade databricks provider dependency databricks-sql-connector to support version >= 3.0

[rubanolha]

Updated the dependency constraint for databricks-sql-connector for databricks provider. It updates the databricks-sql-connector dependency to support version >= 3.0 which is released on Nov 17, 2023. Upgrading to version >= 3.0 is crucial for compatibility with other packages, especially dbt, and resolves a blocker impacting many users' workflows. closes: https://github.com/apache/airflow/issues/39274

As sqlalchemy is optional for databricks-sql-connector starting from v3.0.0, the expectation that it will not be blocked by deprecations of SQLAlchemy 2.

You need to rebase, and fix static checks that are resulting from switching to the new databricks provider.
