What this PR does / why we need it:

This fixes an annoying error I started seeing recently in e2e logs that gets highlighted, e.g. from https://prow.k8s.io/view/gs/kubernetes-ci-logs/logs/periodic-cluster-api-provider-azure-e2e-aks-main/1981117577597816832

 bash: -c: line 4: syntax error: unexpected end of file 

I'm guessing this started with #5883.
