fix(pageserver): more information on aux v1 warnings (#8906)

Browse Source 
Part of https://github.com/neondatabase/neon/issues/8623

## Summary of changes

It seems that we have tenants with aux policy set to v1 but don't have
any aux files in the storage. It is still safe to force migrate them
without notifying the customers. This patch adds more details to the
warning to identify the cases where we have to reach out to the users
before retiring aux v1.
