Adds a blog set up that will make it easy to publish new posts.
You can test this locally by running the `build_blog.sh` script from the
directory of the script. You'll need to have hugo for this, which you
can do in the same way as the Dockerfile:
```sh
RUN mkdir -p hugo-bin && \
cd hugo-bin && \
wget https://github.com/gohugoio/hugo/releases/download/v0.126.1/hugo_extended_0.126.1_linux-amd64.tar.gz && \
tar -xzf hugo_extended_0.126.1_linux-amd64.tar.gz
ENV PATH="${PATH}:/hugo-bin/"
```
