Enable use with Drupal 10

Thanks for the patch.

I will not merge this until it is actually tested and found to work with Drupal 10, I do not want to mark it as Drupal 10-compatible if it actually still has incompatibilities. To install on Drupal 10 and test it, create a fork and install the forked version via composer.

I do not right now have an application that has already upgraded to Drupal 10 that uses this module so it may take me a while until I test it myself. Let us know how it works for you.

I attempted to port this for a client but ran into issues and haven't gotten it working, yet. This is what Upgrade Status reports is needed:

Here I leave an updated patch.

@alexis_mc Before I test this further myself, can you confirm whether you actually tested your patch on a working website? Or is it automatically generated patch?

-    $this->eventDispatcher->dispatch(CartEvents::CARTS_SPLIT, $event);
+    $this->eventDispatcher->dispatch($event, CartEvents::CARTS_SPLIT);
-use Symfony\Component\EventDispatcher\Event;
+use Symfony\Contracts\EventDispatcher\Event;

This means dropping Drupal 8 support, which is fine at this point. The composer/info files need to be updated accordingly. I will create a new branch 1.x for Drupal 9/10 which will be the main branch moving forward, and keep the current 8.x-1.x in a deprecated case for the rare sites that still use Drupal 8.

+        '#uri' => \Drupal::service('extension.list.module')->getPath('commerce') . '/icons/ffffff/cart.png',

We'll need to inject this as a service in the constructor.

Thank you alexis_mc
Your #5 patch fixed almost all issues. But I found a few more.
Rerolled patch with more changes. It works for me.

Confirmed that the patch added in #9 works perfectly.
Thank you.

• New branch 2.x that is compatible Drupal 9.3+/10.0+ and Commerce 2.33+. Commerce 2.33 is the first release that is really compatible with Drupal 10, so we have to set that as minimum version requirement.
• The Save for Later functionality does not seem to work, and it might be a Drupal 10 incompatibility. We have a separate issue for this (#3402287: Error when "Save for later" is clicked) and will resolve this there, but I will not make a release before that is resolved. Until then, applications that do not make use of the Save for Later functionality can use the 2.x development branch.
• Compared to the last patch, I removed the return type declarations; When we move to PHP 8 i.e. Drupal 10 as minimum version requirement, we'll update all code to use PHP 8 features and use strict types wherever possible.
• Compared to the last patch, I removed the change to use the currency formatter. This is still a deprecation until Commerce 3.0, and I want to review this a bit more. We'll work on it on #3410936: Use currency formatter service.
