otelgrpc package should use interceptors in favor of stats handlers

[34fathombelow]

Summary

Otelgrpc dependency (go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc) >= v0.46.0 has deprecated the use of StreamServerInterceptor, UnaryServerInterceptor, and StreamClientInterceptor. Migrating to stats handlers should be performed in a future release of Argo CD to guarantee backwards compatability.

I'm a new contributor. If this is not too difficult, could you assign it to me?

@Jack-R-lantern feel free to take this task - this has been worked on in #17790, but is currently failing the E2E tests...
