chore: setup scripts to update primary language and publication_date

[thepsalmist]

This PR introduces scripts to update the sources table columns first_story and language based on queries from the ES cluster

Addresses #12 #11

This currently exports the results to CSV as follows
language_results_batch_1.csv
publication_date_results_batch_1.csv

Note: When switching this to Django management command within the web_app repo, we'll actually. refactor to fetch the sources directly from the database rather that making the API call

Nice- I like the modularity of this approach, as we think about making other kinds of batch updates to data in the directory. This just exports the changes to a CSV right? I like that approach too, but have you validated the upload loop for that? I've never touched the batch upload paths myself so I'd love to see a validation on a test instance of the web_search.

The structure looks good, here is my early feedback on some few things I observed

This looks good to me! Next step is moving this over to the web_search.
