Separate core and default distribution

We can now separate the AlekSIS core from the default AlekSIS distribution as we now have a private package registry to iinstall dependencies from.

• Remove submodules of apps and the apps/ directory
• Rename this project as well as the PyPI package to AlekSIS-Core
• Change dependencies on AlekSIS to AlekSIS-Core in all apps
• Make poetry depend on packages from EduGit registry only when building in CI
• Create new project AlekSIS for the default distribution
• Move all parts of the default distribution to the new project (including Git history, if possible)
• Move all issues regarding distribution
• Ensure core builds, all apps build, and distribution builds
• Ensure app tests are self-contained
• Ensure pipeline builds are run in the correct order across projects
• Update project and source code locations on OpenHub

All PyPI builds must be published to one project. We can use the new AlekSIS project that holds the distribution stuff for that.
