Better docker deployment strategy

[wearzdk]

This is the PR submitted for #167. I've done some testing and made as small changes as possible to accomplish this feature.

Initially, I used Debian Bookworm for the build and run environments, but some strange errors occurred when running on older systems.
Then, I started to explore building and running it under Alpine, with surprisingly good results: Its final image artifact is now only 20MB! I think that's cool! 🎉

There doesn't seem to be any issue with functionality from my basic testing since the current features aren't too numerous.
I've pushed a latest image to Docker Hub, you might want to give it a try:

docker run -d -p 8000:8000 --name screenshot-to-code wearzdk/screenshot-to-code:latest

To build it locally, run:

docker buildx build -t username/screenshot-to-code .

To push to Docker Hub (need to log in):

docker push username/screenshot-to-code:latest 

You could attempt to build and push it to Docker Hub, then supplement the readme as a deployment solution.
