bsides-sf-ctf-2021/base no longer available

Many of the challenges rely on gcr.io/bsides-sf-ctf-2021/base:latest within the Dockerfiles; however this base image doesn't seem to be available, or at least isn't public.

Can the code or build of that image also be provided within this repository for those wishing to re-use them?

Sorry about that, we should've updated the Dockerfiles to point to a public image. For the moment, if you change to bsidessfctf/base:latest (published on Dockerhub) it's basically the same.
