fix: build and push workflow failing due to missing -f option buildx build command (#425)

I noticed that images on main branch are failing to build (and push) due
to missing `-f` parameter in `docker buildx build`. By default it
expects `Dockerfile` to exist, but we only have `Dockerfile-amd64` and
`Dockerfile-arm64`
