New PRESERVE_STANDALONE_VARIANT strategy for the productVariantsBulkCreate mutation

As of GraphQL API version 2025-10, we have introduced a new value, PRESERVE_STANDALONE_VARIANT, to the ProductVariantsBulkCreateStrategy. This value can be used as an optional argument in the productVariantsBulkCreate mutation.

The PRESERVE_STANDALONE_VARIANT strategy ensures that any existing standalone variant, whether default or custom, is retained when executing the productVariantsBulkCreate mutation.
