toTOML incorrectly renders nested tables.

[elnoxgdl]

When using toTOML function when rendering secrets that were stored in vault when transforming the map to TOML it incorrectly renders the nested tables.

Take this as example.

The original data stored in vault:

{
  "metrics": {
    "prometheus": {
      "enabled": true
    }
  }
}

Using this template:

{{ with secret "secrets/staging/service.toml" -}}
{{ .Data.data | toTOML }}
{{- end }}

Renders:

[metrics]
  [metrics.prometheus]
    enabled = true

The spec for TOML states that nested tables should be [x.y] I don't understand what's the problem.
