 When upgrading from PHP 7.X to PHP 8.X, there might be a `Fatal error:
 Uncaught ArgumentCountError: Too few arguments to function
 WP_Widget::__construct()` error. This will prevent access to the entire
 website, including the admin area. The fix is, however, quite simple:

 In `/wp-includes/class-wp-widget-factory.php` change line 62 from

 {{{#!php
 <?php
 $this->widgets[ $widget ] = new $widget();
 }}}

 to

 {{{#!php
 <?php
 $this->widgets[ $widget ] = new $widget( $widget, $widget );
 }}}

 Discovered and tested in WordPress version 6.5.4 when upgrading from PHP
 7.4 to 8.2.
