Build Data workflow (2020PB/police-brutality)

# This is a basic workflow to help you get started with Actions
 
name: Build Data
 
# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the main branch
on:
  push:
    branches: [ main ]
  # Pausing the build on pull_request because it seems these cause a duplicate build which can fail.
  # I added this event because it seemed sometimes `push` was not causing a build.
  # So I'm leaving these comments until it's verified that `push` alone is good.
  #pull_request:
  #  types: [ closed ]
  #  branches: [ main ]
 
# A workflow run is made up of one or more jobs that can run sequentially or in parallel
