Data Dumps: Add Sentry error logging

[cclauss]

As discussed in several issues related to #5402 our data dumps can be quite tricky so this PR logs data dump error output into Sentry to ease debugging.

Chatted on call:

• Separate type hint changes into new PR --> Type hints for openlibrary/utils/sentry.py #6329
• Create a new Sentry Project/DSN in UI, ol-cron-jobs
  • https://sentry.archive.org/organizations/ia-ux/issues/?project=12#welcome
• Add sentry_cron-jobs section to openlibrary.yml so that can have other DSN
• Move the Sentry(...) call to the __main__ so it doesn't run on like import

Note we might need to pass in the path to the openlibrary.yml; I can't recall if importing it this way does the magic for local/prod environment.

Code lgtm (excluding that typo :P )! Can you try testing it by running the dump.py script locally, and copying the dsn into your local openlibrary.yml? Should see first event appear in sentry UI :)

Tested on call with Chris running it locally with correct DSN; appeared in sentry UI 👍

Need to test a full data dump as well later
