[LucasDemea]

Describe the bug When activate the plugin using wp cli, an error occurs indicating that a wrong argument type was passed to the activate function.

To Reproduce

1. Install plugin
2. Activate plugin using wp-cli

Expected behavior The plugin activates without throwing any error

Additional context

PHP Fatal error:  Uncaught TypeError: Argument 1 passed to My_Plugin\Backend\ActDeact::activate() must be of the type bool, null given, called in /var/www/html/wp-includes/class-wp-hook.php on line 307 and defined in /var/www/html/wp-content/plugins/my-plugin/backend/ActDeact.php:62

What I found It seems that in some cases a null value is passed to the activation hook. Therefore, the activate function shouldn't limit its argument type to boolean.
