Missing description in FieldType declaration

@dipakmdhrm, Its a duplicate issue & the solutions was already given.
Ref : https://www.drupal.org/project/drupal/issues/3409413 🐛 Error TypeError: Drupal\Core\Field\FieldTypeCategory::getDescription() if a FieldType has 'description' missing in its annotation RTBC

This module still needs to add a description to the annotation.

The MR here works for me and I am able to access the add new field page.

I had the same issue.
Applying the patch from the MR solved the issue.
