Plugin Updater Check does not detect PUC library usage

[ernilambar]

The look_for_plugin_updaters() function in Plugin_Updater_Check does not detect plugins that use the YahnisElsts Plugin Update Checker library.

Example code that is currently not detected:

$update_checker = YahnisElsts\PluginUpdateChecker\v5\PucFactory::buildUpdateChecker(
	'https://example.com/plugin-info.json',
	__FILE__,
	'my-plugin-slug'
);

Current code:

$look_for_regex = array(
	'#\'plugin-update-checker\'#',
	'#WP_GitHub_Updater#',
	'#WPGitHubUpdater#',
	'#class [A-Z_]+_Plugin_Updater#i',
	'#updater\.\w+\.\w{2,5}#i',
	'#site_transient_update_plugins#',
);

This pattern uses the YahnisElsts\PluginUpdateChecker\v5\PucFactory::buildUpdateChecker() static method to add custom update functionality, which is not permitted.
