Dockerfile and build instructions broken with recent changes

[mddeff]

With 8d9a0fe, the docker file build does not work according to the docs.

Docs say to:

git clone https://github.com/snstac/adsbcot.git
cd adsbcot/
docker build -t adsbcot .

Errors out on not being able to find a Dockerfile

Even referencing the file directly (with -f docker/Dockerfile), looks like some of the other resources are now relative to the docker directory, specifically

-COPY adsbcot-docker-example.conf /etc/adsbcot/adsbcot.conf
+COPY docker/adsbcot-docker-example.conf /etc/adsbcot/adsbcot.conf
 
-COPY start.sh /start.sh
+COPY docker/start.sh /start.sh

Also, is there any objection to adding a Github workflow to build the docker container on every tag and push to ghcr?

It wouldn't cost anything for the project (because it's public) and would make it easy for folks to just pull the image (rather than always having to build it locally).

I'd be happy to provide a PR - would just steal from something like my meshtastic-map or ioquake containers
