AssertionError: "General" must be defined in MODULE_NAME.field_type_categories.yml in assert()

Problem/Motivation

After installing and enabling this module, when I try to add a field to a node entity type, I get the following error:
AssertionError: "Algemeen" must be defined in MODULE_NAME.field_type_categories.yml in assert() (regel 183 van /var/www/html/web/core/lib/Drupal/Core/Field/FieldTypePluginManager.php).

Steps to reproduce

- Add module via composer (Add the dev version to a Drupal 11 project)
- Enable module
- Try to add a field to a node type

Proposed resolution

Edit signaturefield/src/Plugin/Field/FieldType/SignatureFileItem.php line 17 and change category to signature:
* category = "signature",

Edit signaturefield/src/Plugin/Field/FieldType/SignatureItem.php line 16 and change category to signature:
* category = "signature",

Create signaturefield.field_type_categories.yml in the module folder:

signature:
  label: 'Signatures'
  description: 'Field to store Signatures.'
