Adding a deploymentLabel map causes an error

[EvilSmiff]

When deploying tofu-controller using the chart v0.16.0-rc.5 using a HelmRelease manifest with the following specified in the values: key

values: deploymentLabels: app.kubernetes.io/part-of: flux app.kubernetes.io/version: v2.4.0
I'm getting the following error:

Running 'install' action with timeout of 5m0sHelm install failed for release flux-system/tofu-controller with chart tofu-controller@0.16.0-rc.5: YAML parse error on tofu-controller/templates/deployment.yaml: error converting YAML to JSON: yaml: line 13: mapping values are not allowed in this context

I'm not certain as I've little experience on helm templating but this appears to be due to a minor error in the helm template code in https://github.com/flux-iac/tofu-controller/blob/main/charts/tofu-controller/templates/deployment.yaml on line 7.

Using the same values block but setting the deploymentLabels to podLabels doesn't cause the error.
