Revert "add a github action for build multi-arch docker images (#1574)" (#1591)

This reverts commit 26274633660a372429abee7be4b0ae1f7c13c0e1.

## Issue Addressed

This is a temporary fix for #1589, by reverting #1574. The Docker image needs to be built with `--build-arg PORTABLE=true`, and we could probably integrate that into the multi-arch build, but in the interests of expediting a fix, this PR opts for a revert.
