🐛 Bug Report: [Regression] Members list empty when there are confirmed members

[awanlin]

📜 Description

The members list on the Group view is empty even though we can see there are members by looking at the User view

👍 Expected behavior

The member list should be populated with the proper members

👎 Actual Behavior with Screenshots

The member list is empty for all Groups. For example "Breanna Davidson" is part of Team A - https://demo.backstage.io/catalog/default/user/breanna.davison. When you look at Team A the member list is empty- https://demo.backstage.io/catalog/default/group/team-a

👟 Reproduction steps

1. Create a backstage instance
2. View a Group

Notice: the member list is empty

📃 Provide the context for the Bug.

This is a regression as we previously could see the members of the group in this view

Did some digging into this as it got mentioned on Discord and seemed odd: https://discord.com/channels/687207715902193673/1179775361366626345. I've been able to confirm that it works in the current 1.20.3 release so it must be a change in one of the 1.21.0-next.x releases

From my very basic investigation if I console.log the membersList.items from this line I get and empty array:

backstage/plugins/org/src/components/Cards/Group/MembersList/MembersListCard.tsx

Line 178 in 701fdd4

const membersList = await catalogApi.getEntities({
