[DONE] Data Dashboard Tutorial - Uplink issue

Hi! Just spotted a small documentation issue in Chapter 5, Step 2 of the Data Dashboard.

Issue
The code provided in Step 2 does not have an anvil.server.wait_forever(), so the client running uplink will not remain open.

Repro:
Run Chapter 5 and it will fail to retrieve data from the client running Uplink

Fix:
The code block provided in Chapter 5, Step 2 should be:

import anvil.server

anvil.server.connect(" your-uplink-key")

@anvil.server.callable

def get_marketing_data():

    # access data on your local machine and return as a Python list

    return [{'strategy':'Strategy A', 'count':200}, 

            {'strategy':'Strategy B', 'count':185}, 

            {'strategy':'Strategy C', 'count':175}]

anvil.server.wait_forever()

Nice catch – updated!
