outdated documentation in aws console

On this page "Getting started with AWS X-Ray":
https://eu-west-1.console.aws.amazon.com/xray/home?region=eu-west-1#/getting-started

the recommendation is to use an outdated version:

```
*pom.xml*

com.amazonaws
aws-xray-recorder-sdk-core
1.2.1

```

While the dev guide proposes to use the outdated version 2.2.0:
https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-java.html?icmpid=docs_xray_console

These kind of documentation should be aligned to the current version 2.3.0, otherwise it just leads to unnecessary confusion.

Thanks!
