Current Behavior

We forgot to add the planned i18n support to #530.

Expected Behavior

i18n can be used for auto-created child node labels.

Steps To Reproduce

The following configuration should show the localised labels

'Neos.Demo:Content.Columns.Two':
  ...
  childNodes:
    column0:
      type: 'Neos.Demo:Collection.Content.Column'
      label: i18n
    column1:
      type: 'Neos.Demo:Collection.Content.Column'
      label: i18n

Environment

- Flow: 8.4
- Neos: 8.4
- PHP: 8.3

Anything else?
