Add “change author” functionality

Hey @byronveale.

I think you can use hook_form_alter() in your custom module.
Example:

/**
 * Implements hook_form_alter().
 */
function replicate_actions_form_alter(&$form, FormStateInterface $form_state, $form_id): void {
  if (strpos($form_id, '_replicate_form')) {
    /** @var \Drupal\replicate_actions\Form\ReplicateFormAlter $replicate_form_alter */
    $replicate_form_alter = \Drupal::service('replicate_actions.replicate_form_alter');
    $replicate_form_alter->alterForm($form, $form_state);
  }
}

Or implement your own EventSubscriber:
class ReplicateChangeAutor implements ReplicateSetEntityEdit.

However, if you can create a patch, I will add this functionality to the module. I think it is a great idea.

@byronveale, brilliant. I am going to review tomorrow. Thank you.

Hi, Steps to Reproduce the Issue and Verify the Fix

Tested on Drupal 11.2.3.
Installed and enabled Replicate and Replicate Actions modules.
Created two users:
User A → can create content
User B → can replicate content

Logged in as User A and created a Page (/node/add/page).
Logged in as User B, went to the Page created by User A, clicked Replicate, and saved the replicated page.

Before applying the patch: The replicated page author was User A (original author).

Applied MR !12, cleared cache with drush cr, and repeated the same steps.

After applying the patch: The replicated page author is now User B (replicating user).

Its working fine. Thanks.

Thank you @byronveale, @bkosborne and @vinodhini.e.
Merget to master.
