_load_textdomain_just_in_time incorrectly called and now shows notice

[PeteAUK]

Description of Problem

Since the upgrade to Wordpress 6.7.0+ simple lightbox now generates the following error:

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the simple-lightbox domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later

It would appear that previously calling _load_textdomain_just_in_time could be called outside the init action, however this is no longer the case.
