Fixed Function in Templates.php

[DAnn2012]

Description

This PR updates the save_button definition in Popup Maker by replacing esc_attr__() with esc_attr_e().

• esc_attr__() returns the translated string but does not output it directly.
• esc_attr_e() both translates and immediately echoes the string, which is the expected behavior in this context.
• This ensures that the "Add" label is properly translated and directly rendered in the button output.
