Changes proposed in this Pull Request:

This PR fixes the CashApp Pay and Digital Wallet payments on Block Checkout for WooCommerce 9.3. The issue was occurring only with WooCommerce 9.3, and I suspect it's due to the React 18 upgrade in WC 9.3. The token updates in the state are not reflected in onPaymentSetup when onSubmit is called.

This PR fixes the issue by replacing onSubmit(); with setTimeout( onSubmit, 0 );, breaking out of the current event loop to ensure state updates in onPaymentSetup. We are having an ongoing discussion with the Woo Team to figure out the proper fix. However, with WC 9.3 releasing tomorrow, proceeding with this fix for now is fine.

Closes #214

Steps to test the changes in this Pull Request:

1. Upgrade to WooCommerce 9.3(-rc-1)
2. Try placing an order using CashApp pay from block checkout and verify its works as expected.
3. Try placing an order using Digital wallets (GooglePay and ApplePay) from block checkout and verify it works as expected.

Code looks good to me. As discussed internally, Woo may be making changes in 9.3 that would remove the need for us to make this change. Going to hold off on moving this forward until we know for sure their decision

Going to close this out since the issue was resolved in Woo 9.3 itself and this fix is no longer needed
