The new task does a few things:
1. Having an extra build target makes the workflow file cleaner
2. it downloads the release targets which we want to build docker images for
3. it extracts the tar files into sub folders. We need to extract into sub folders to so that our image can fine the binaries. By providing `platform` to `docker buildx` the variable `TARGETPLATFORM` will be available when building the image. This variable is either `linux/amd64/`, `linux/arm64/` or `linux/arm/v7`. Hence we need to extract into subfolders.
4. We create 2 images, one for the maker and one for the taker. The images are then pushed to our organisation's docker registry.
These are mostly copy-pasted from xmr-btc-swap modulo the changelog
handling (because we don't have a changelog).
The gist is:
- We attach release binaries to every release that is created.
- Every merge to master creates a `preview` release.
- A merge from a branch that is named `release/x.y.z` creates a
release `x.y.z`.
- A new release branch can be created via `draft-new-release.yml`.
