Remove `no_run` from as many documentation code example as possible

## Brief feature description

If the example code is also run, we can ensure that the example is also functional working. Therefore, we should remove the `no_run` tag from as many documentation code examples as possible.

Comment from @elBoberido :

@elfenpiff there is also the option for ignore. Those could then be run on a single platform, just in case the reason for no_run is platform dependent code in the lower layers
