"No payment method provided" error at checkout if cart total is 0

[dubfonik]

Describe the bug

Using the Checkout block, if cart total is 0 (either by produce price or use of a coupon), and no payment methods are defined, the checkout cannot be completed. Error No payment method provided appears.

I am able to proceed if using the standard [woocommerce_checkout], but not with the new WooCommerce Block version

To reproduce

Steps to reproduce the behavior:

1. Disable payment methods
2. Add a $0 product, or use a coupon code with 100% discount
3. Attempt to checkout

Expected behavior

We should be able to checkout if the cart total is 0.

Environment

• Core version: [e.g. 5.8.1]

Desktop (please complete the following information):
