Feat monorepo

[like-a-bause]

Description

• uses workspaces to create a monorepo.
• adds https://turbo.build/repo to define dependencies between elements / examples and builds accordingly

You may have to delete the different node_modules folders/ package-lock.json to get this working.

If you don't run on M1 you have to install turbo globally:

npm install turbo --global

Additional context

[like-a-bause]

I implemented 2 workspaces. One top level, including examples/ and frontend/ and on in frontend/. The second one is only for use in the Docker build process, because the Dockerfile can only access ./ but not ../ so we need a package.json in ./

As @bjoern-m suggested, we could move the examples into the frontend folder to reduce the complexity here.
What do you think?
