Upgrade gRPC and OpenTelemetry packages for compatibility (#2003)

Upgrades `go.opentelemetry.io/otel` from version` v1.11.1` to `v1.26.0`. The upgrade addresses compatibility issues caused by the removal of several sub-packages in the latest OpenTelemetry release, which were causing broken dependencies.

**Key Changes:**
- Upgraded `go.opentelemetry.io/otel` from `v1.11.1` to `v1.26.0`.

- Fixed broken dependencies by replacing the deprecated sub-packages:
  - `go.opentelemetry.io/otel/metric/instrument`
  - `go.opentelemetry.io/otel/metric/instrument/asyncint64`
  - `go.opentelemetry.io/otel/metric/instrument/syncint64`
  
- Upgraded `google.golang.org/grpc` from `v1.56.3`  to `v1.64.0` which deprecate `Dial` and `DialContext` to `NewClient`.
