Fix Streamlit app.yaml

[maucaro]

The command element removed extraneous entries and now looks like:

command:
  - "streamlit"
  - "run"
  - "app.py"

This fixes "App not available" upon deployment.

Entries in the env element now look like:

env:
  - name: DATABRICKS_WAREHOUSE_ID
    valueFrom: sql-warehouse

This fixes the following error: "Error deploying app: error reading app.yaml file"

The following prompt was used to generate an app.yaml file: "create an app.yaml file for a databricks streamlit app"

The newly created file was tested with a new Streamlit App without any issues.
