Profile changed in config or content don't update the instance entity

Problem/Motivation

When an instance is created, it is with a profileId property:

  /**
   * Display Builder profile ID.
   */
  protected string $profileId = '';

However, after creation of the instance, this property is never updated, even when the related property is updated by WithDisplayBuilderInterface implementations on config or content.

Proposed resolution

This property as a setter : InstandeInterface::setProfile(), Let's use it.
