Stabilize test workspace creation in automated test pipelines

Default start workspace timeout = 5 minutes is too small when run automated devfile tests agains DS deployed to OCP on PSI OSP where network lags are observed from time to time, e.g.:
https://main-jenkins-csb-crwqe.apps.ocp-c1.prod.psi.redhat.com/job/Testing/job/e2e/job/basic/job/typescript-tests/1763/consoleFull

Solution: increase start workspace timeout using config of devworkspace operator controller [1]:

cat <<EOF | oc apply -f -
apiVersion: controller.devfile.io/v1alpha1
kind: DevWorkspaceOperatorConfig
metadata:
  name: devworkspace-operator-config
  namespace: openshift-operators
config:
  workspace:
    progressTimeout: "10m"
EOF
