I attempted to upgrade to testcontainers-scala 0.15 and I get this error:

Exception encountered when invoking run on a nested suite - {"message":"Get https://registry-1.docker.io/v2/bsideup/moby-ryuk/manifests/0.2.2: unauthorized: incorrect username or password"}

I have no idea what it means or why it's failing but it is. I've downgraded back to 0.13 for the time being.

No repository file or test is named. Start by reproducing the testcontainers-scala 0.15 upgrade and tracing the nested suite's pull of bsideup/moby-ryuk:0.2.2, using the HttpResponseHandler stack entry as a starting point. Done means identifying the cause of the registry authentication failure and verifying a fix with a regression check.
