Field length is not respected when live editing

Merge Request !13 introduces a data-me-max_length data attribute, which the "basic" JavaScript editor uses to enforce field length limits. Here are a few key points:

1. This functionality applies only to "basic" editors and does not support CKEditor 5-enabled fields.
2. Enforcing character limits in CKEditor 5 is not straightforward and requires custom solutions.
3. CKEditor 5 is not the default editor for short formatted text fields in Drupal. It is only available for fields that use "textarea" form inputs.
4. This approach adds a custom data attribute (data-me-max_length) using the max_length setting from the field definition. Developers who want to define custom limits for field lengths can use a custom implementation of the hook_preprocess_field function to add the data-me-max_length data attribute with the desired value.
