Changes proposed in this Pull Request:

Updates the experiment name for the latest WC Release.

Partially addresses #44643 .

How to test the changes in this Pull Request:

1. Open your console and go to Application > Local Storage and make sure the item with key: explat-experiment--woocommerce_product_creation_experience_empty_state_updates_202403_v1 is removed or does not exist.
2. Go to the ExPlat experiment woocommerce_product_creation_experience_empty_state_updates_202403_v1 and choose the variation you want to test. ( Note: When testing each version make sure you have the product editor feature flag disabled. For example when it is enabled the task list will ignore the experiment and always redirect to the new editor, meaning that testing the control version doesn't seem to work ).
3. When hovering over any Bookmarklet link of control or treatment variation, a popover should appear with instructions to try one of the variations ( redo step 1 when switch treatment versions ).
4. Be sure to save the suggested link to your browser bookmarks.
5. Go to WooCommerce > Home and go through the OBW ( Onboarding workflow ) or skip it.
6. Go to /wp-admin/admin.php?page=wc-admin and click on the second item to add a new product.
7. Click on the bookmark saved in step 3.
8. After clicking the saved bookmark, a modal with this title should be shown ExPlat: Successful Assignment
   Close the modal.
9. Click on any of the product types ( test a couple ).
   If you chose the "control" variation, you should see the old/legacy product form.
   If you selected the "treatment" variation, you should see the blocks product editor.
