Fires before a particular screen is loaded.

The load-* hook fires in a number of contexts. This hook is for plugin screens
where a callback is provided when the screen is registered.

The dynamic portion of the hook name, $page_hook, refers to a mixture of plugin
page information including:

  1. The page type. If the plugin page is registered as a submenu page, such as for
    Settings, the page type would be ‘settings’. Otherwise the type is ‘toplevel’.
  2. A separator of ‘page‘.
  3. The plugin basename minus the file extension.

Together, the three parts form the $page_hook. Citing the example above,
the hook name used would be ‘load-settings_page_pluginbasename’.
