  This PR just shows how to do a deterministic build for `arm64` architecture. The hope is HWI's support for `arm64` will improve a bit.

  ### Setup

  To set up your environment, install:

  ```s
  sudo apt install qemu-user-static
  ```

  ### Build for arm64

  Use [docker buildx](https://docs.docker.com/buildx/working-with-buildx/) to replicate [deterministic build instructions](https://github.com/bitcoin-core/HWI/blob/master/docs/development/release-process.rst#deterministic-builds-with-docker) for the arm64 build:

  ```s
  docker buildx build --no-cache --platform linux/arm64 -t hwi-builder -f contrib/build.Dockerfile .

  # Note the use of "--without-gui".
  docker run --platform linux/arm64 -it --rm --name hwi-builder -v $PWD:/opt/hwi  --workdir /opt/hwi hwi-builder /bin/bash -c "contrib/build_bin.sh --without-gui && contrib/build_dist.sh --without-gui"
  ```

  i.e. the change is:

  ```diff
  -docker build --no-cache -t hwi-builder -f contrib/build.Dockerfile .
  -docker run -it --name hwi-builder -v $PWD:/opt/hwi --rm  --workdir /opt/hwi hwi-builder /bin/bash -c "contrib/build_bin.sh && contrib/build_dist.sh && contrib/build_wine.sh"
  +docker buildx build --no-cache --platform linux/arm64 -t hwi-builder -f contrib/build.Dockerfile .
  +docker run --platform linux/arm64 -it --rm --name hwi-builder -v $PWD:/opt/hwi  --workdir /opt/hwi hwi-builder /bin/bash -c "contrib/build_bin.sh --without-gui && contrib/build_dist.sh --without-gui"
  ```

  ## Limitations

  ### No GUI support

  So far I had no luck with building `hwi-qt` because I get the following error

  ```

  That's why I use `build_bin.sh --without-gui` (see #655)
