Query bakery sales data using SQL agent

The "bakehouse" schema in the samples catalog in Databricks contains fabricated data about bakery sales. We can create a LangChain Databricks SQL agent to connect to this dataset and then ask the agent queries about the data. The agent can use SQL to get the answers and can show it's work, describing the SQL queries and logic used to get to the solution.
