@alamb could you trigger the CI . also I think there might be need for running ./dev/update_function_docs.sh as I think its halting in my machine .

thanks @Adez017

To get the examples updated in md files it would be needed to update Documentation builders

Thanks for suggestion mate I fired ./dev/update_function_docs.sh but I think its not working on my machine as I didn't get the successfully updated message in terminal . because of this particular reason I think someone need to do that @comphead @alamb also previously it checked 27 CI jobs , so I think we need to trigger that CI also

I think I accidentally merged this without running update_functions_docs.sh first 😢 (I thought the CI was green, but clearly I misread the UI)

I will make a follow on PR to fix
