Fix: #14

1. 🎩 💁‍♂️ to @sidewinder12s for discovering that our error metrics were attempting to capture on the wrong metric 😬 , this fixes that by sending errors to the correct errors metric
2. discvered how out of date skaffold was, so updated that
3. while i was in there update to go 1.21

I didn't add a test for the failing case (I did verify this by lowering my docker timeouts and failing the request). Happy to split this up if it's too much
