Add reference application for new Getting Started

[svrnm]

Hey there,

after a few months of silence I finally got back to the project for a new getting started app. I merged the specification for the reference app into the oteldotio repo, and now I am looking for language SIGs that go ahead and implement it:

• https://opentelemetry.io/docs/getting-started/reference-application-specification/
• https://github.com/open-telemetry/opentelemetry.io/blob/main/content/en/docs/getting-started/reference-application-specification.md

With this dedicated examples repository, I think java is a good language to start with!

Thanks:-)

The Java implementation would be most useful if it pins the reference-spec revision and can be verified end to end with a local Collector plus deterministic backend assertions, not only screenshots. A single command should start the app, generate the specified traces/metrics/logs, and check required attributes and context propagation. Keeping dependency versions aligned with the Getting Started docs will also prevent the example from demonstrating APIs different from the page that links to it.
