patch from MR diff

The following error when adding or editing shipping methods:
Error: Class "FedEx\RateService\SimpleType\RateRequestType" not found in Drupal\commerce_fedex\Plugin\Commerce\ShippingMethod\FedEx->defaultConfiguration() (line 213 of /var/www/html/web/modules/contrib/commerce_fedex/src/Plugin/Commerce/ShippingMethod/FedEx.php)

You'll probably need to remove the D10 compatibility stuff and keep the patch to just this issue.

I realize it's easier for the end user to have all the stuff in one patch, but it's easier for maintainers to review just the fix at hand.

I think FedEx is deprecating their old API supported by this library.

There is a new API and a new wrapper for it at https://github.com/WhatArmy/FedexRest

@greggles you're right. I've done some progress with migrating to WhatArmy/FedexRest and created new issue https://www.drupal.org/project/commerce_fedex/issues/3417970 📌 Migrate to WhatArmy/FedexRest Active .

Since SOAP based support is ending in a couple months, Closing this in favor of 📌 Migrate to WhatArmy/FedexRest Active .
