Add mechanism to make sure the example applications work before merging

[thrbnhrtmnn]

Description / User story

We had issues in the example application(s) before, after merging component changes, which we did not cover with our current tests. Therefor we should extend our tests to cover the example application(s) as well. We can also reach the goal with something else than with unit test. One idea is to prevent merging if compiling the example application does not work.

Requirements / Prerequisites

• none

Acceptance Criteria

• We implemented a test, that prevents us from merging branches if the example application breaks

Additional information

• We could do this by changing the example application to typescript and see if compiling it works

Code of Conduct

• I agree to follow this project's Code of Conduct

This task is now easier to do after #1096 . The only things we need to do now:

• use typesafe render functions in example application
• setup mandatory built task in github workflows
