datalayer_field_config_submit not valid callable on new field creation

Problem/Motivation

After updating core to 11.3.2 and Datalayer to 2.1.1, an attempt to create a new field on a Paragraph type results in an error in browser console and in the site error log as php error:

InvalidArgumentException: The callable definition provided "[datalayer_field_config_submit]" is not a valid callable. in Drupal\Core\Utility\CallableResolver->getCallableFromDefinition() (line 69 of /code/web/core/lib/Drupal/Core/Utility/CallableResolver.php).

A revert of the Datalayer update, back to 2.1.0, resolves this and a new field can be created without error.

Steps to reproduce

With Drupal 11.3.2, Paragraphs 8.x-1.20, Datalayer 2.1.1:

- Create a new field (I created a plain text field, unformatted), save;
- On the next form for configuration settings for the field, click save.

For me the form does not save or close, there is an "oops" message in the browser, an error in the browser console, and the above php error in the site's error log.

Revert Datalayer to 1.1.0 and creating/saving a new field is error free.
