Please add "string" to field types

Problem/Motivation

I often use plain text ("string") fields with custom max length over 255. Actually even 255 is long enough to span multiple lines.

Proposed resolution

Add "string" to src/Plugin/Field/FieldFormatter/ExpandableFormatter.php

/**
 * Plugin implementation of the 'expandable formatter' formatter.
 *
 * @FieldFormatter(
 *   id = "expandable_formatter",
 *   label = @Translation("Expandable"),
 *   field_types = {
 *     "text",
 *     "text_long",
 *     "text_with_summary",
 *     "string_long",
 *     "string"
 *   },
 * )
 */

I did exactly that and it works as expected on plain text fields.
