Make repo public

We need to either make this repo public or move it to the tensors_private group. This is per the following annoucement from GitLab:

GitLab announced storage and user limits on the GitLab SaaS Free tier. The new storage and user limits will not be enforced prior to 2022-10-19. Storage usage includes all types of storage including Repository, LFS, Packages, and Registry with a limit of 5GB per namespace for the Free tier. You can view your storage usage on the Settings Usage Quota Page.
