Some data files from a previous run of this action are created with root as the owner. Because the action runs as a non-root user, such files are [not able to be deleted](https://github.com/cmu-delphi/forecast-eval/runs/3351290227?check_suite_focus=true) which is needed for the actions/checkout@v2 step to install the newest version of the repo. This seems to be a bug in the actions/checkout@v2 command, perhaps specific to self-hosted workflows. [Summary of issue](actions/runner#691) and [suggested fixes[(actions/checkout#211).

Description
Some (but oddly not all) data files from a previous run of this action are created with root as the owner. Because the action runs as a non-root user, such files are not able to be deleted which is necessary for the
actions/checkout@v2step to install the newest version of the repo.This seems to be a bug in the
actions/checkout@v2command. Summary of issue and suggested fixes.This problem seems to happen rarely (this is the first occurrence). It is unclear why it started happening -- the checkout action hasn't released a new version recently, and our workflow and code haven't changed.
This fix changes the owner of the directory from root to the actions working user so that the user is allowed to delete it (requires passwordless sudo or password stored in GitHub Actions secrets).
