Subscription creation example doesn't work on API 2025-03-31.basil

Bug report

Describe the bug

Subscription can't be created on 2025-03-31.basil because of this change
https://docs.stripe.com/changelog/basil/2025-03-31/add-support-for-multiple-partial-payments-on-invoices#use-for-payment-element-integrations

instead of expand: ['latest_invoice.payment_intent']
it should be expand: ['latest_invoice.confirmation_secret']

instead of

res.send({
      subscriptionId: subscription.id,
      clientSecret: subscription.latest_invoice.payment_intent.client_secret,
    })

it should be

res.send({
      subscriptionId: subscription.id,
      clientSecret: subscription.latest_invoice.confirmation_secret.client_secret,
    })

To Reproduce

Try to change

const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY, {
  apiVersion: '2022-08-01',

to

const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY, {
  apiVersion: '2025-03-31.basil',

and create a subscription. It will fail because subscription.latest_invoice.payment_intent will be null.

Can confirm the case, worked for me only as subscription.latest_invoice.confirmation_secret.client_secret

With latest_invoice.payment_intent returned as null.

subscription.latest_invoice.confirmation_secret.client_secret saved my endless search why it didnt work, thank you for that!
