Missing completions for section locales

Describe the bug
When using the locales object in a section schema, those locales aren't surfaced as completion suggestions

Source

// section/test-section.liquid

{{ 'sections.test-' }}

{% schema %}
{
  "name": "Section",
  "locales": {
    "en": {
      "title": "Title"
    }
  }
}
{% endschema %}

Expected behaviour
Whilst typing 'sections.test-' in the tag at the top, 'sections.test-section.title' | t' should be suggested, like with locales defined in locales/*.json

Actual behaviour
Nothing is suggested

Reproduce completion in section/test-section.liquid using the provided schema, then compare it with locale entries from locales/*.json. Trace how the editor discovers translation keys and ensure section-schema locales produce the expected sections.test-section.title suggestion; verify the original example no longer returns no suggestions.
