Add .com renewal banner to group and subgroup pages

Overview

With our work on #102 (closed), we did not add the banner to the group and subgroup pages.

Proposal

Add the banner display logic to:

• group page
• subgroup page
• project within a subgroup page

Example of a group: https://gitlab.com/gitlab-org
Example of a subgroup: https://gitlab.com/gitlab-org/database-team
