.github: Rename failure step in actions

Currently, the way that GitHub renders failing jobs here is that the
"Install cilium chart" step will fail, then the "Capture cilium-sysdump"
step will be collapsed. Recently we added `cilium status` output into
this step, but unless developers know to click on this step and expand
the output to investigate the cluster status, it's not obvious whether
the failure is a random CI issue or whether there is some cause related
to their changes.

Renaming the failure step here will hopefully give a slightly better
signal to developers when a failure is caused by their changes, and that
they should take a closer look at the sysdump to confirm the failure
condition.
