Please fix this translation issue

In some places in your code you use esc_attr with translation text domain

i.e. public/class-mwb-bookings-for-woocommerce-public.php line 618, line 622, line 636 and line line 640 (placeholders)

These texts are not translatable since esc_attr one recieve one parameter esc_attr( string $text )

You need to use esc_attr_e which recieves the second parameter as a text domain.

Please don’t forget to update the po file,

Thanks.
