Fix extraContainers in Cron helm chart

[nightmareartist]

What

If current chart is used with extraContainers enabled the deployment will fail with the following error message:

Error: YAML parse error on cron/templates/deployment.yaml: error converting YAML to JSON: yaml: line 94: did not find expected key

This is not a problem when global extraContainers is used, but if, for example, we want Cron specific sidecar containers the setup will fail.

How

Added proper indentation to line 154.

Can this PR be safely reverted / rolled back?

This is still an active issue. Could we please get this merged in and fixed? The proposed change from nindent 6 to nindent 8 is valid.

Thanks!
