Milestone page list redesign

Design from https://gitlab.com/gitlab-org/gitlab-ce/issues/35833

Project milestone list page

• For project milestones in this page, there are links to the actual project milestone for that project.
• For group milestones, date information is currently not being shown. Date information should be added. Use a design similar to https://gitlab.com/gitlab-org/gitlab-ce/issues/39542.

Group milestone list page

• e.g. https://gitlab.com/groups/gitlab-org/milestones
• Some of the milestones are group milestones. Others are project milestones. So display that accordingly.
• The milestones in "Closed" tab have a "Closed" label in the background-color $red-500 :: DB3B21

Open	Close

Dashboard milestone list page

• e.g. https://gitlab.com/dashboard/milestones

• This is currently only showing project milestones and not showing any date information. Add the date information. Use a design similar to https://gitlab.com/gitlab-org/gitlab-ce/issues/39542.

• Implement the new visual design.

Status of milestone

• The milestone has the different badges depends on the status.
