Put the SSO login option on top

[Lwanda-SIfolo]

Hey guys.

how do enable this option,

$enabledloginchoices = [ \theme_snap\output\core_renderer::ORDER_LOGIN_MOODLE_FIRST => new lang_string('moodleloginfirst', 'theme_snap'), \theme_snap\output\core_renderer::ORDER_LOGIN_ALTERNATIVE_FIRST => new lang_string('alternativeloginfirst', 'theme_snap') ];

we want to move the alternative/SSO option on top, and then Moodle native login bellow

Thanks
