Fix the issues reported by phpcs

This patch will fix the code standard issues.

Let me review it.

Please review.

It would also help to know the command used for that report and which arguments have been used. In that way, maintainers can check if the report is complete or correct for the 8.x-1.x branch.

The report is not for the current code in the 8.x-1.x branch. In fact, this is the code used in that branch.

• Line 94
  $attributes = $options['attributes'] ?? [];
• Line 114
  $default_value = $attributes[$attribute] ?? NULL;

This change means options are no longer translatable anymore, so in this case the issue reported is wrong and can be ignored
