What does this MR do and why?

When adding member guidelines in the appearance, in the Group Members view, the text would overflow and move the invite buttons far out of the window. This was caused by the member guidelines being added to with_actions, however it should have been added to with_description. This is correctly handled in the Project members view.

How to set up and validate locally

From the issue:

1. In Admin area -> Settings -> Appearance, add a Lorem Ipsum paragraph to the Member Guidelines field:

Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.

2. Create a test group and go to the Manage members page. Observe the Invite buttons are not visible. Scroll to the right to see the Invite buttons.
