Issue title: Admin can hide archived Projects, or they are always hidden
 Issue body: ## User story 
As a Collective admin, I want to be able to archive no longer active Projects so they don't take up space on my page and people aren't confused by seeing them.

## Best solution for this problem
Either a per-Project setting to optionally hide it that activates when a Project archived, or a default global choice to hide all archived Projects for non-admins.

## MVP
Being able to request the dev team to hide specific archived Projects from view at the request of users via support.

 Comment 0: Related to #4640 - if we implement hiding them all then we don't need to worry about sending them to the end of the order.
 Comment 1: I decided to contact some creators or archived Projects and ask them if they would prefer them to be hidden or not. I'll update the results of this informal survey here.
 Comment 2: I've heard back from a few users and so far they all prefer archived projects are always hidden from non-admins. This also seems like a simpler solution to implement since we don't need a setting for it.

To me it really makes sense because if for some reason someone wants to deactivate a project without it disappearing, they can simply remove all contribution tiers and leave it un-archived.
 Comment 3: We have consensus from everyone asked that admins want archived projects to be hidden. Is there any way this could be done soon, as @Betree said it would be simple? This is blocking people from promoting their Projects page because there's stuff on there that is inactive and confusing.
 Comment 4: @alanna Since https://github.com/opencollective/opencollective-frontend/pull/7058, archived projects are normally displayed only to admins. Everyone else only sees the active ones (as per the specifications in https://github.com/opencollective/opencollective/issues/4836#issuecomment-945208792). Was there anything more to do to complete this issue?
 Comment 5: Ah ok, I didn't know. Is this documented? Can we add a tooltip for admins somehow? They are unlikely to figure this out because to them they look visible.
