Remove non-adjacent duplicate csharp-no-url-suffix suppressions

6 properties (botservice x4, cost-management x2) had csharp-no-url-suffix suppressed twice with a pre-existing casing-style suppress between the two, so they were non-adjacent and missed by the first dedup pass. Collapse to a single csharp-no-url-suffix suppression per property.
