Description
This iterates on #36089, which
logged us into DockerHub during unit tests in order to reduce how often
DockerHub rate-limits us.
Forks will fail to log into DockerHub unless the fork owner configures their
own DockerHub creds. This PR is an attempt to make it so that unit tests don't
fail when DockerHub login fails.
Testing instructions
With DockerHub credentials...
Just see this PR's build.
Without DockerHub credentials...
I merged these changed to master of my personal fork, which has no DockerHub credentials configured.
Here is a PR against my personal fork demonstrating that the modified unit-tests action tolerates failure of the Docker Log In step: kdmccormick#31
