adding a new trait for user attribute

[atmonshi]

I added a new trait for getting the user name

so you have to add this to your user model:

use \LaraZeus\Bolt\Models\Concerns\BelongToBolt;

This will allow you to get the user name by another attribute like full_name

PR Summary

• Updated Documentation
  Additional guidance has been provided in installation.md and upgrade.md regarding the usage of Bolt Trait in the User Model. This makes the software easier to install and upgrade.

• Enhanced Functionality in View Pages
  Changes have been made in both browse-entry.blade.php and show-entry.blade.php files to display the full name of the user instead of the avatar image. This improves the user's ability to make associations and references in regards to contributors.

• Improved Response Management
  Modifications in ResponseExporter.php and ManageResponses.php files enable managing responses using the full name of the user. This results in better organization and easier reference of responses.

  A new BelongToBolt trait has been added through the BelongToBolt.php file under the Models/Concerns directory. This trait simplifies getting the full name of a user, aiding in user identification.
