Make gondle examples work again

[ernscht]

Issue: The examples no longer work in CodeSandbox environments. Current Error message: "Invalid Host Header"

Current solution: The examples are pulled directly from the GitHub repo (CodeSandbox pulls from master branch). However, Code-Sandbox is constantly being modified, so these examples are currently no longer working.

Wanted Maybe we'll get this solution working again. Also ideas are welcome for alternative solutions.

This fix solved most of the issues. Most examples work again, thanks a lot @stefanibus

There remain two other problems:

module not found:
