The interface for `ArgResults` from `package:args` has added new fields. Change the implementations of these in the conductor to extend `Fake` so that these aren't analyzer errors.
This broke the pub roll here: https://github.com/flutter/flutter/pull/146642#issuecomment-2050169629
Fixes https://github.com/flutter/flutter/issues/129744
This change:
1. re-enables the Linux packages_autoroller
2. ensures we redact the token from appearing in any logs (in local testing I realized some failure logs might still expose the token)
What actually fixed authentication however was creating and uploading a new GitHub personal access token, not this change.
It's currently failing post-submit because being marked `bringup` it is running in the try pool, which does not have permissions to access the cloud KMS. However, I ran a LED build in the prod pool that succeeded:
