Java Context API example uses the wrong context

[teofr]

What needs to be changed?
The Java Context API site has an example where the current context instead of the local one should be used.

What is the name + path of the page that needs changed?
content/en/docs/languages/java/api.md

Additional context:
Tiny fix, just not worth signing a CLA. See #5752

Thanks for the find. Code for the excerpt lives over here: https://github.com/open-telemetry/opentelemetry-java-examples/blob/main/doc-snippets/api/src/main/java/otel/ContextUsage.java#L39

I'll get to this soon enough, but just sharing in case anybody beats me to it.
