Problem:
We are showing warnings when edits are made via SpecialPages to Entities 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.
This applies for all edits to Entities that are done via SpecialPages.

Example

In the example above 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.
When IP masking is enabled the message should read:

By clicking "Create", you agree to the terms of use, and you irrevocably agree to release your contribution under the Creative Commons CC0 License.
If you log in or create an account, your edits will be attributed to a username, among other benefits.

But the warning should remain as is on wikis that don't have IP masking enabled e.g. 3rd party Wikibases
When IP masking is not enabled it should continue to read:

By clicking "Create", you agree to the terms of use, and you irrevocably agree to release your contribution under the Creative Commons CC0 License.
Warning: You are not logged in. Your IP address will be publicly visible if you make any edits. If you log in or create an account, your edits will be attributed to a username, among other benefits.

BDD
GIVEN an Entity
WHEN making an edit to them via a Special Page
AND IP Masking is enabled
THEN do not show the IP leak warning

Acceptance criteria:

• IP leak warning isn't shown when editing Entities via SpecialPages when IP Masking is enabled
