Need to update Docker Images

[atoomic]

I just noticed the deprecation warning from a pipeline using the docker images

Example: Dual-Life/autodie#121

[DEPRECATION NOTICE] Docker Image Format v1 and Docker Image manifest version 2, schema 1 support is disabled by default and will be removed in an upcoming release. Suggest the author of docker.io/library/perl:5.8 to upgrade the image to the OCI Format or Docker Image manifest v2, schema 2. More information at https://docs.docker.com/go/deprecated-image-specs/

Looks like the Dockerfile need to be adjusted and images rebuilt.
