In the case you hit some API error (Github ratelimit was often a problem) or the instance restarted in the middle of your migration, you would be left with data on the disk and/or database. Upon retrying the migration the migration code would (rightfully) fail because it's trying to migrate stuff that already exists.
This was hit so often on Codeberg it was better to force people to delete and start whole migration process again: 28ee60c91f
Delete the repository data before retrying to solve this.

- Follow up of forgejo/forgejo!5041, forgejo/forgejo!6074, forgejo/forgejo!8692
- The `task` table contains three secrets: clone address (with credentials), auth password and auth token. These secrets are stored for migrating repositories (also the only usage of this table, although it allows for more usages).
- Use `keying` to safely store these secrets and bound them to the table, column, row id and JSON field name.
- The migration isn't spectacular but does closely follow what we learned in the previous two migrations: use a transaction and delete records when you can't decrypt them. We also learned about `db.Iterate` not being happy when updating records but it has since been fixed.
