Consider the possibility to set emptyText to ArrayField or to it's children component

Is your feature request related to a problem? Please describe.

This request is a follow up of #6179.

Using the empty field of the Datagrid component is a solution. however, this field require only a react component.

This may be useful for some cases, but it is completely overkill if you just want to show a "It is empty" text just like other simple fields.

We may also use empty={<span>It is empty</span>}, however, we loose all the react-admin design of the Fields (Typography with specific config).

Describe the solution you'd like

Having a way to just put a emptyText props on a ArrayField, making the configuration much simpler:

<ArrayField
  source="userDiscountCodes"
  label="Codes promos associés"
  emptyText="Aucun"
>
  <Datagrid empty={<TextField emptyText="Aucun." />}>
  </Datagrid>
</ArrayField>

Or, if the ArrayField usage is a problem, maybe on the Datagrid component itself (and any of the usable children):

<ArrayField
  source="userDiscountCodes"
  label="Codes promos associés"
>
  <Datagrid emptyText="Aucun.">
  </Datagrid>
</ArrayField>

Describe alternatives you've considered

The only solution I found to get the exact same render with a minimal "code copy/paste" impact is this:

<ArrayField
  source="userDiscountCodes"
  label="Codes promos associés"
>
  <Datagrid empty={<TextField emptyText="Aucun." />}>
  </Datagrid>
</ArrayField>

Additional context

A side note about the last change: the emptyText was reported as not used for the ArrayField. However, this option is still present on the TS definition. Is it a wanted behavior?

[soullivaneuh]

I have an another case with no solution, using the ChipFieldList:

<ReferenceArrayField
  source={source}
  label={label}
  reference="users"
  {...props}
>
  <SingleFieldList linkType="show">
    <UserIdentityChipField />
  </SingleFieldList>
</ReferenceArrayField>

The emptyText also has no effect (expected) but I don't have any empty field for this child.

How should I resolve this case? 🤔
