Update Dockerfile:

- The build now happens in the container itself, uisng node:20-alpine as the build stage
- A special artifacts stage is created (but won't be used unless specifically called) to create the archive files, used as the releases
- Switched from httpd to nginx

The image is still very light (16.9MB)
