Subject: [PATCH] Add Dockerfile (#1211)

* Add Dockerfile

To simplify building on Linux:

```console
docker build -t sourcery-image .
docker run sourcery-image sourcery --help
```

I've kept the resulting Docker image small(-ish) at the expense of
probably removing some useful functionality. I haven't tested this
thoroughly but I'll leave it to other contributors can expand this as
needed.

* Simplfy build flags

Since the runtime image is also Swift.

* Add CI job to build and publish docker images to GitHub Packages

Will run on commits to the `master` branch and tags.
