Recipe for adding bash to Kaniko

[BeyondEvil]

FROM curlimages/curl:8.7.1 as base

RUN curl -sSLo "bash" "https://github.com/robxu9/bash-static/releases/download/5.2.015-1.2.3-2/bash-linux-x86_64" && \
    chmod +x bash

FROM gcr.io/kaniko-project/executor:v1.21.1-debug as final

COPY --from=base /bash /busybox/
RUN ln -s /busybox/bash /bin/bash

Obviously, you can play around with ARGs to make the versions dynamic.
