   *   An associative array of replacements. Each array key should be the same

   *   as a placeholder in $string. The corresponding value should be a string

   *   or an object that implements \Drupal\Component\Render\MarkupInterface.

   *   Null args[] values are deprecated in Drupal 9.5 and will fail in

   *   Drupal 11.0. The value replaces the placeholder in $string. Sanitization

   *   and formatting will be done before replacement. The type of sanitization

   *   The args[] value replaces the placeholder in $string. Sanitization and

   *   formatting will be done before replacement. The type of sanitization

   *   and formatting depends on the first character of the key:

   *   - @variable: When the placeholder replacement value is:

   *     - A string, the replaced value in the returned string will be sanitized
