Modernize from Annotation to Attribute

Using workflow 2.1.4 with 10.2.12 I get the following message

docker@cli:/var/www$ drush cr

In FieldConfigStorageBase.php line 31:

Unable to determine class for field type 'workflow' found in the 'field.field.fiss_booking.fiss_booking_training.field_fbt_status' configuration

In DiscoveryTrait.php line 53:

The "workflow" plugin does not exist. Valid plugin IDs for Drupal\Core\Field\FieldTypePluginManager are: address_zone, address_country, address, comment, commerce_plugin_item:commerce_condition, commerce_plugin_item:commerc

There is also the bigger issue that not many Attributes were supported before the 10.3.0 release and hence Works with Drupal: ^8.8 || ^9 || ^10 || ^11 and Works with Drupal: >=8.8 really should be Works with Drupal: ^10.3 || ^11 and a decision made about the upper version for the 8.1-1.x branch.

Let me see what I can do.

I am still confused how core upgrades affect contrib upgrades. I do not like to maintain/test multiple branches.
After investigating the change record again and the code base (see updated issue summary),it seems I can just restore the original code, additionally to the new Attributes for "workflow" plugin.

Ofcourse, then there is no benefit from the code.

I will not do any updates to v1.x. v1.8 is revoked.

Please try latest 2.1.x dev version.

the following is added to the summary:

[...] According to this drupal core change-record:
RenderElement and FormElement base plugin classes are deprecated and renamed to RenderElementBase and FormElementBase →

The current Attributes in WorkflowItem causes dumps in installations, e.g. in 11.2-dev.
So this will be removed in the following commit.
