[2.0.x] Layout Builder Lock

For these applications, we need a project where, in at least a branch, most of the commits (but preferably all the commits) have been done from the person who created the application.
The purpose of these applications is reviewing a project to understand what the person who applies understands about writing secure code which follows the Drupal coding standards and correctly uses the Drupal API, not what all the project maintainers collectively understand about those points.

Updated issue, added link to branch

@Panchuk Most of the commits have been done by other maintainers.
