fascinating!
does this use the previous training from the old labeler by any chance or do we start over?

You have to re-train but now it's all self-service within each repository, and no services to run, storage to manage, or anything else outside GitHub Actions. But the logic for building the new model is the same as the old implementation (but muuuuuuuccch faster and easier). When you run the 'Labeler: Training' job, the job summary will show the new model's accuracy based on test results where it re-predicts existing issue/pulls in the repository and compares the new prediction against the existing labels.

These workflows replace the issue-labeler implementation that runs as a GitHub app, allowing training and prediction for the repository's labels without the need for an external service.
References:
Once this is merged, we'll need to run the 'Labeler: Training' workflow to train new prediction models, then 'Labeler: Promotion' workflow to promote the models into active use, and then I can decommission the integration of the legacy issue-labeler app for this repo.
The legacy issue-labeler was also applying the untriagedIssues and PRs which have not yet been triaged by a lead
label to new issues and pull requests, but there's also a
resourceManagementpolicy in this repo for managing the untriaged label. With this migration to the GitHub Action based issue-labeler, the issue-labeler will no longer apply that label, so only the resource management policy will apply for that.
