Draft: Feat add arm support to image

What does this PR do? (Please give us a brief description of what this PR does.)

This PR is an attempt to get ARM builds working ( https://git.joinfirefish.org/firefish/firefish/-/issues/8555)

I haven't used kaniko to build images ever, so this is a bit trial and error. Im opening the PR already to be able to run the pipelines though, as I don't have any runners I could use for my personal fork
