Change the domains in fulcio config map to match each other

[therealnb]

Summary

This change is to address a startup issue in fulcio. See details at #622

Release Note

This is a small change of config. This looks like it might have been fixed twice because there are sections in the scripts like this

# Install Fulcio and wait for it to come up
echo '::group:: Install Fulcio'
if [ "${NEED_TO_UPDATE_FULCIO_CONFIG}" == "true" ]; then
  echo "Fixing Fulcio config"
  cp config/fulcio/fulcio/200-configmap.yaml ./200-configmap.yaml
  # The sed works differently in mac and other places, so just shuffle
  # files around for now.
  sed 's@https://kubernetes.default.svc.cluster.local@https://kubernetes.default.svc@' config/fulcio/fulcio/200-configmap.yaml > ./200-configmap-new.yaml
  mv ./200-configmap-new.yaml config/fulcio/fulcio/200-configmap.yaml
fi
make ko-apply-fulcio
echo '::endgroup::'

Where the change in this PR would be reverted for k8s < 1.24.

Hmmm, different versions different behaviour. Needs investigation...
