Added 'staged' field and deprecated 'publish' field on EmbeddedPriceImport and ProductVariantImport

To simplify the process of importing Embedded Prices and Product Variants, we have added the staged field to EmbeddedPriceImport and ProductVariantImport. With this new staged field you can control whether the imported data should be applied to the current and/or staged representation of the Product to update.

The staged field replaces the publish field, which is now deprecated and will be removed on 1 August 2024.

This change brings the Import API in line with the HTTP API by using the same fields for the same purpose. If you are using the publish field to import Embedded Prices and Product Variants, you should use staged instead and adjust the value based on your use case.

Changes:

• [API] Added staged to EmbeddedPriceImport.
• [API] Added staged to ProductVariantImport.
• [API] Deprecated publish field on EmbeddedPriceImport.
• [API] Deprecated publish field on ProductVariantImport.
