The message wikimedia-globalrenamequeue-email-body-rejected and its translations include angle brackets. The angle brackets were probably added to make sure that the URL doesn't get mixed with other characters. However, the CI suspects that the angle brackets are HTML and requires a manual review of every translation update that includes a translation of this message.
The URL should be moved to a separate line, which is enough for isolation. This will be more readable, too (because URL are often very long).
