Set dotnet E2E test target for dotnet sdk v1.3.2 and cloudwatch helm charts v2.2.0 (#309)

*Description of changes:*
Set current .NET SDK release for .NET E2E tests instead of the latest
version because the new ADOT .NET SDK release will introduce breaking
changes. It will prevent E2E test failures during release process.
- EC2 test target : [ADOT .NET SDK
v1.3.2](https://github.com/aws-observability/aws-otel-dotnet-instrumentation/releases/tag/v1.3.2)
- K8s test target: [Amazon CloudWatch Observability Helm Chart
v2.2.0](https://github.com/aws-observability/helm-charts/releases/tag/amazon-cloudwatch-observability-2.2.0)
