Hotfix: `give_goal` and `give_form` display the goal progress correctly

[JoshuaHungDinh]

Resolves #6563

Description

The PR removes a get_id() Wordpress function in the give_goal shortcode. The function is not needed and causing the shortcode to fail when rendering. It was an oversight from PR https://github.com/impress-org/givewp/pull/6541. Because the Legacy template relies on give_goal to display the goal progress - fixing the issue in give_goal has corrected the issue with give_form while using a legacy template.
