Update Redirects should report the redirects that were marked as invalid

**Description**
The content client should report the failed redirects.

**To Reproduce**
Currently the content client return the response from the content sdk, but there are urls that are already filtered out because they are either duplicates or create cycles.

**Expected behavior**
contentClient.updateRedirects should inform how many urls were updated and how many failed

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Additional context**
Add any other context about the problem here.

Locate contentClient.updateRedirects and inspect how it currently returns the Content SDK response. Trace how duplicate and cyclic URLs are filtered, then add coverage showing that the method reports both updated and failed redirect counts.
