Migrate container image builds to GitHub Workflows

* Migrate from the internal Drone server using a GitHub Workflow
to perform the multi-arch container image build
* Use self-hosted GitHub runners on ARM64 to perform the ARM64
build step faster that QEMU/KVM emulation
* Mandate approval for all workflow runs from outside contributors
since the builds use push credentials and partially run internally
