### Describe the bug

I created a form with amplify studio.
In that form i use a relation to another model, which is why an Autocomplete component is included in the form.
However, the Autocomplete component gets wrapped in an ArrayField by Amplify Studio.
While the Autocomplete component has set hideLabel=true, the outer ArrayField is responsible for rendering the label for the construct.
The problem now is, that we cannot override the label for the ArrayField. ArrayField simply misses the line:
{...getOverrideProps(overrides, "FIELDNAME")}

### Expected behavior

Something like
{...getOverrideProps(overrides, "FIELDNAME_container")}
should be included in the outer ArrayField, so we can properly access the label of an Autocomplete Component.

### Reproduction steps

1. Create a graphql schema with two Models with a relation
2. Create a form using Amplify Studio
3. Import that form into your REACT project
4. Try to override the label for the resulting Autocomplete field

### Additional information

As a workaround, i simply put
{...getOverrideProps(overrides, "FIELDNAME_container")}
in the auto-generated form and am now able to access the label and translate it.

Start by reproducing the relation-based form in Amplify Studio and inspect the generated Autocomplete and surrounding ArrayField. Confirm that the outer ArrayField lacks the reported override prop, then verify that overriding FIELDNAME_container changes the generated field label as expected.
