Allow data Streams enrich policies (elastic#200903)

Closes [elastic#187438](elastic#187438)

## Summary

This PR introduces the data streams as source indices in the enrich
policies. For that, it uses the groups functionality, so the indices are
separated from the data streams.

### Strings
I've changed some of the existing strings but left other as they were.
I'll be happy to also change those if folks feel that should be the
case.

I've added a hint text and changed the label for the box in the creation
step (marked in yellow)
<img width="400" alt="Screenshot 2024-11-20 at 12 35 32"
src="https://github.com/user-attachments/assets/794a7063-3f75-4f3d-996c-12ca8b9ed9b6">

I haven't change the label for the indices group (green) and I've
followed the same structure for the new group category (yellow)
<table>
  <tr>
    <td style="padding-right: 10px;">
<img alt="Screenshot 2024-11-20 at 12 37 51"

    </td>
  </tr>
</table>

I haven't change the 'Source indices' text in the Summary (green)
because in the request tab the correspondan field in the request is
indices (blue)
<table>
  <tr>
    <td style="padding-right: 10px;">
<img alt="Screenshot 2024-11-20 at 12 38 53"

    </td>
  </tr>
</table>

I also haven't change the 'Source indices' text in the table or in the
detail flyout (green) since both indices and data streams are treated
like indices.
<table>
  <tr>
