Show preview of delete contributions when deleting user in admin
Summary
As pointed out by @cynthia there are 2 ways to delete a user, the Delete user and all contributions
will end up deleting everything, groups, projects.
Sometimes it's not clear what "All contributions" mean here, and we can accidentally delete groups/subgroups and projects without the admin user knowing.
Proposal
Show a preview of the contributions that are going to be deleted. For users, it might be expensive to count everything, but if we can at least list the number of projects and groups, and then a general statement of what else might be included like comments?
