[Bug]: TransactionLineItemPreview is missing Proration details

[shadeon]

What happened?

When previewing a subscription change that generates immediate proration, the relevant immediateTransaction.details.lineItems do not include proration details such as the rate and billing period.

The docs and usage of the API directly includes a null or object as appropriate, but they are missing entirely from this package.

Steps to reproduce

1. Create a subscription with recurring items.
2. Attempt to preview a subscription modification lowering the quantity using paddle.subscriptions.previewUpdate() with the prorationBillingMode set to prorated_immediately

What did you expect to happen?

Proration details for any existing items that result in a credit are included in the immediate transaction line items. Otherwise, the property is null as documented and via the API directly.

Hi @shadeon, thanks for raising this, we'll look into this and provide an update soon

@shadeon there is a dependency on another project that needs to be updated first and then we'll be able to get this sorted, thanks for your patience
