Documentation Tasks for first Iteration

[Aklakan]

• Add overview page of general concepts and settings: set version from current time, attach resources to artifact, resource folders; properties: maven.install.skip, docker.skip.build, maven.resources.skip (untested whether it would skip our data builds)
• Document Webdav-based deployment using https://maven.apache.org/wagon/wagon-providers/wagon-webdav-jackrabbit/ (not ideal because of deprecation but I tested it against Nextcloud and it worked)
• Try out whether Maven Polyglot works for our use case and document the results (e.g. see https://www.baeldung.com/maven-polyglot) -> works!
• Document mvn+docker-based data generation

• based on the coypu disasters dataset
• also find out whether the setup could be improved such that the docker image is built once rather than on every run. maybe we need 2 profiles - one to build the image and one to run it.

• Document deploy-on-change.sh script (ideally the script would be replaced with a maven plugin that e.g. could set the maven.deploy.skip property to false if the artifact already exists)
