[PATCH] Shipping method entity definition references a non-existing class as translation handler

The reason I looked at that class was a hard-to-reproduce crash in a custom project with the error message:

In EntityTypeManager.php line 256:

The "commerce_shipping_method" entity type did not specify a translation handler.

That sometimes leaves the system in a broken state until I run `drush cr` again until it succeeds.
Since it is not happening every time I cannot tell yet if removing that line will fix my issue,
but referencing a non-existing class seems wrong in any case.

This is the original issue when this change got introduced... ✨ Shipping method entity does not support translations Fixed .

The missing class can be found in this comment: https://www.drupal.org/project/commerce_shipping/issues/2934142#comment-... ✨ Shipping method entity does not support translations Fixed .

So I think we should commit the missing handler instead of removing it.

As soon as you modify the general content translation settings you end up with this exception and parts of the site become unusable and throw the same exception:

Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException: The "commerce_shipping_method" entity type did not specify a translation handler. in Drupal\Core\Entity\EntityTypeManager->getHandler() (line 256 of core/lib/Drupal/Core/Entity/EntityTypeManager.php).

Also drush cr doesn't work anymore.

Re #4: Of course, that's better. I had looked for issues about the translation handler but didn't come across that one.

Revert accidental prio change.

And the status.

We will integrate this patch into our project and report back.

I added patch #5 to our system and the exceptions went away.

Committed! Will tag a new release.

Automatically closed - issue fixed for 2 weeks with no activity.

When I try to clear cache with drush I get the below error. Drupal10 and php 8.1

In EntityTypeManager.php line 256:

  The "commerce_shipping_method" entity type did not specify a translation handler.

Also this is causing the site to constantly give WSOD
