 Here's an example of how the updated WordPress admin panel could look:

---------------------------------------------------------
|                                                         |
|                       Dashboard                         |
|---------------------------------------------------------|
|                                                         |
|    Posts         Media        Pages        Comments     |
|                                                         |
|    Plugins       Themes       Users        Settings     |
|                                                         |
|    Contribute                                          |
|                                                         |
--------------------------------------------------------

The following code snippet demonstrates a simplified example of how to add the "Contribute" tab to the WordPress admin panel:

function add_contribute_tab() {
    add_menu_page(
        'Contribute',
        'Contribute',
        'manage_options',
        'wordpress-contribute',
        'contribute_page_callback',
        'dashicons-megaphone',
        30
    );
}

function contribute_page_callback() {
    // Content for the Contribute page goes here
}

add_action('admin_menu', 'add_contribute_tab');
