chore: [k212] fix: remove retries on the stats handlers because they already retry

[grafanabot]

Backport 1008315 from #13608

---

What this PR does / why we need it:

#13584 added retries to the stats handlers because I had seen some 5xx errors on stats functions not being retried. it was pointed out we already have retries on the statshandler, the tripperware used here already includes it.

Instead it seems the 5xx's that were not retried were fixed in #13592 so this PR removes the duplicate retry
