helm-tool inject sometimes omits the context (prefix) of commented out values in the generated markdown

[wallrj]

In https://github.com/cert-manager/approver-policy/pull/383 I originally added a new block to the end of the existing values.yaml file:

> podDisruptionBudget:
>   # Enable or disable the PodDisruptionBudget resource.
>   #
>   # This prevents downtime during voluntary disruptions such as during a Node upgrade.
>   # For example, the PodDisruptionBudget blocks `kubectl drain`
>   # if it is used on the Node where the only remaining approver-policy
>   # Pod is currently running.
>   enabled: false
> 
>   # Configures the minimum available pods for disruptions.
>   # Cannot be used if `maxUnavailable` is set.
>   # +docs:property
>   # minAvailable: 1
> 
>   # Configures the maximum unavailable pods for disruptions.
>   # Cannot be used if `minAvailable` is set.
>   # +docs:property
>   # maxUnavailable: 1
> 

But when I ran make generate-helm-docs it added minAvailable and maxUnavailable as global values, rather than prefixed like podDisruptionBudget.minAvailable .

It seemed to only be a problem when the commented out values were the last in the file. Adding a trailing foo: bar or moving the new block above some other existing blocks fixed the problem.
