Fix invalid schema definition

@Grevil: I think this can't be fixed in the module here, but must be fixed in the field providing module!

The icon field is provided by the micon module, I think?

@Grevil: Yes this is a Micon issue!

This is the track:
https://git.drupalcode.org/project/micon/-/blob/2.x/src/Plugin/Field/Fie...
class StringMiconItem extends StringItem

=>

https://api.drupal.org/api/drupal/core%21lib%21Drupal%21Core%21Field%21P...

  /**
   * {@inheritdoc}
   */
  public static function defaultStorageSettings() {
    return [
      'max_length' => 255,
      'is_ascii' => FALSE,
    ] + parent::defaultStorageSettings();
  }

So I think it's a micon schema error and we need to create an issue and fix over there.

@Grevil: Eventually we can simply unset these keys like here:
https://git.drupalcode.org/project/drupal/-/blob/11.x/core/lib/Drupal/Co... but then we'd have to be sure it has no side effects.

I looked into core, where these values are being handled in the schema and it's here:
https://git.drupalcode.org/project/drupal/-/blob/11.x/core/config/schema...

Now the question is, why the schema isn't inherited on Micon fields extending this.

Any I think the best way to find the solution is to find a similar case, where a contrib module (with pretty schema) also extends a core field type?

Are you on the track with this information @Grevil?
