build: add docker support (#75)

* feat: add Dockerfile to run application in container

Added Dockerfile with .dockerignore to streamline use of enex2notion.
User can now build an image with '$ docker build -t <image_name>:>tag> .'
Data volume is declared at /data, which client can map to the host
directory where the .enex files reside.
Entrypoint already specifies the launch script, all left to do is to add
CLI arguments.

* docs(readme): add info about building docker images

Added section with commands to build a docker image from the source
as well as run it.

* build: update Dockerfile

* ci(github): add container release workflow

* docs(readme): add info about docker

* docs(readme): move docker info higher

+### With [**Docker**](https://docs.docker.com/)
+
+This command maps current directory `$PWD` to the `/input` directory in the container. You can replace `$PWD` with a directory that contains your `*.enex` files. When running commands like `enex2notion /input` refer to your local mapped directory as `/input`.
+
+```shell
+$ docker run --rm -t -v "$PWD":/input vzhd1701/enex2notion:latest
