examples for aspire standalone only expose 4317 (grpc) and not 4318 (http)

Describe the issue or suggestion

The otel spec https://github.com/open-telemetry/opentelemetry-specification/blob/v1.28.0/specification/protocol/exporter.md#specify-protocol has changed -- gRPC is no longer the suggested default for SDKs.

SDKs SHOULD support both grpc and http/protobuf transports and MUST support at least one of them. If they support only one, it SHOULD be http/protobuf. They also MAY support http/json.

If no configuration is provided the default transport SHOULD be http/protobuf unless SDKs have good reasons to choose grpc as the default (e.g. for backward compatibility reasons when grpc was already the default in a stable SDK release).

Please update the examples to expose the 4318 port -p 4318:18890

Flagging @JamesNK for visibility.

I think it's fine to have all the dashboard docker run commands expose both.

Closing as a non-issue.
