For anyone coming across this in 2021 the solution is to set a textdomain via code like so:
add_action('acf/init', 'acf_l10n_textdomain_setting');
function acf_l10n_textdomain_setting()
{
acf_update_setting('l10n_textdomain', 'yourtextdomain');
}
Once this setting is defined it will automatically wrap them on export.
