Unhide CI instructions when dependencies need regeneration (apache#38748

)

The instructions on what to do was hidden in a folded group and we
need to make sure it is printed straight in the output.

Also we should not print the nasty traceback, as it is not very
useul, the failing python command already prints appropriate
error/informational messages and there is no need to clutter the
output with the traceback when the command fails.
