Describe the bug
Action group on index page with inline display throws twig exception:
Variable "group" does not exist in @EasyAdmin/crud/action_group.html.twig at line 3.

To Reproduce

1. Add an action group the the index page.
2. Display the actions inline.

(OPTIONAL) Additional context
Index page with inline actions loads the action_group.html.twig template directly without converting the twig variable action to group.
