Update payment.md code sample to require ./index.js

[marleypowell]

The description paragraph mentions:

It then requires your app at ./index.js to start it up once the SDK is initialized.

https://github.com/open-telemetry/opentelemetry.io/blob/9b9596e21766406b0d93b203fd1bf184f831111e/content/en/docs/demo/services/payment.md?plain=1#L21C1-L25C24

This seems to be missing from the code sample.

This is not correct. What is missing is how you require this, which is done as part of the node command to start the app itself.

node --require ./opentelemetry.js index.js

What would it look like in the Dockerfile?

ENTRYPOINT [ "node", "--require", "./opentelemetry.js", "./index.js" ]

This PR in its current form, is not correct. The docs today are also not correct. See this comment on what the proper solution is, which would also require rewriting the paragraph description on the docs page: #4256 (comment)
