Multi-arch builds (#32)

* feat: enable multi-arch builds and add tor and i2p images

This commit introduces multi-architecture support (amd64 & arm64)
for Docker image builds using Docker Buildx. It also adds new
images for tor and i2p services. The release script is updated to
handle these new images and to accept a Docker Hub username as an
argument. The publish workflow is updated to use the new release
script and to set up QEMU and Docker Buildx.

* feat(publish.yaml): add workflow_dispatch trigger to publish workflow
feat(publish.yaml): allow publish workflow to run when workflow_dispatch event is triggered

* feat(dockerfiles/monero): add support for ARM64 architecture

* build(dockerfiles/monero): remove duplicate FROM instruction

release(monero)
