Only update errored venues on retry

[joshuayoes]

Currently, if anything at all goes wrong with the yarn start script, we retry the whole script. However, typically it's only one or two venue websites that are the issue.

With retry-step action, we can run a different command on re-runs after failure: https://github.com/marketplace/actions/retry-step#run-different-command-after-first-failure

We could set a list of error-ed venues on retry, and then run a new command with a filter to retry only the failed venues.
