Added key to Embedded Prices and Embedded PriceDrafts, and an update action to set keys for both Standalone and Embedded Prices

In addition to identifying Embedded Prices by their id, you can now use key as a user-defined unique identifier. By assigning a human-readable key to Embedded Prices, you have greater flexibility for referencing Embedded Prices.

The key field was already available for StandalonePrices and this allowed us to assess and confirm its usefulness. Implementing the key field in Embedded Prices ensures consistency in offerings for both Standalone Prices and Embedded Prices.

Update actions for setting the key value has also been added for both Embedded Prices and Standalone Prices, allowing you to efficiently update Price keys without needing to bulk import Prices with the updated price keys.
