fullnameOverride variable not included in values schema of lacework-agent helm chart

[richugs]

The fullnameOverride variable which is used on line 15 of the _helpers.tpl file in the lacework-agent helm chart is not included in the values.schema.json which means we're unable to use the variable without turning off schema validation.

Line where it's used https://github.com/lacework/helm-charts/blob/e573b06ae5340e7d45afce2bf1a00b9c49b9e1aa/lacework-agent/templates/_helpers.tpl#L15C16-L15C32
