Support for docker build secrets

[toshi38]

Is there any plans (or objection to a PR for) docker build secrets https://docs.docker.com/build/building/secrets/

I imagine it could work something similar to the official docker build/push action: https://github.com/docker/build-push-action?tab=readme-ov-file#inputs (see secrets, secret-envs, secret-files)

Or perhaps there is some other recommended path or mechanism that already supports secrets?
