User story:
As a Wikidata administrator about to perform a delete action,
I want to know which "Wikis subscribed to this entity",
in order to assess my decision more efficiently.

Problem:
Currently, I can only access the information about which "Wikis subscribed to this entity" on the "Page information".

Solution:
Show the deleting Admin a warning message about which "Wikis subscribed to this entity".

Acceptance criteria:

• Show warning message with a list of "Wikis subscribed to this entity".
