[Issue] Clarified Attribute Option already exists response

[m2-assistant]

This issue is automatically created based on existing pull request: #39941: Clarified Attribute Option already exists response

---

Description (*)

Replaced the awkward phrase "Get new file name if the same is already exists" with a clearer and grammatically correct version: "Get a new file name if one already exists." This improves readability and user understanding.
Same for the attribute option response.

Manual testing scenarios (*)

1. pushing an already existing attribute option to the attribute option api endpoint.
