Problem:
We are showing warnings when on the Set Item sitelink page and the user isn't logged in. This warning informs them that their IP will be shown. With IP Masking this will no longer be the case so we should remove the warning.

Example

On the Set Item sitelink page only the IP warning should be removed.
i.e. "Warning: You are not logged in. Your IP address will be publicly visible if you make any edits."

This should only be removed only when IP masking is enabled and the user isn't logged in.

But the warning should remain as is on wikis that don't have IP masking enabled e.g. 3rd party Wikibases

BDD
GIVEN a user who isn't logged in
WHEN setting an Item sitelink
AND IP Masking is enabled
THEN do not show the IP leak warning

Acceptance criteria:

• IP leak warning isn't shown when on the Set Item sitelink page and IP Masking is enabled
