Error: Call to undefined method Drupal\Core\Field\BaseFieldDefinition::getThirdPartySettings

Problem/Motivation

Seems that Custom Entity that extend ContentEntityBase with file managed does not have third party settings

Error: Call to undefined method Drupal\Core\Field\BaseFieldDefinition::getThirdPartySettings() in file_field_replace_field_widget_single_element_form_alter() (line 134 of modules/contrib/file_field_replace/file_field_replace.module).

Steps to reproduce

Create a Custom Content Entity and add a field with File managed:

$fields['icon'] = BaseFieldDefinition::create('file')
      ->setLabel(t('Icon'))
      ->setSetting('file_extensions', 'svg png')
      ->setDisplayOptions('view', [
        'label' => 'above',
        'type' => 'image',
        'weight' => 7,
      ])
      ->setDisplayOptions('form', [
        'type' => 'image_image',
        'weight' => 7,
      ])
      ->setDisplayConfigurable('form', TRUE)
      ->setDisplayConfigurable('view', TRUE);

Proposed resolution

Update the check on the function file_field_replace_field_widget_single_element_form_alter to validate if the field definitions has the function getThirdPartySettings.
