iu_banner view requires group module and shouldnt

Problem/Motivation

When enabling the module from a clean install, the following error happens:

  The "group_id_from_url" plugin does not exist. Valid plugin IDs for Drupal\views\Plugin\ViewsPluginManager are: entity_browser_widget_context, node, taxonomy_tid, current_user, user, fixed, query_parameter, raw

The group_id_from_url plugin is from the Group module, but this module should not be a dependency of this module if possible.

Proposed resolution

Remove the `group` display from the `iu_banner` view yaml export.
