Contributes to #3229, this updates the tracing instructions to follow a similar path what we have for some other languages already (JS was the example I took for reference).

Ditto.


The example also sets up the mandatory SDK default attribute `service.name`,
which holds the logical name of the service, and the optional (but highly
encouraged!) attribute `service.version`, which holds the version of the service

I think I've left similar comments in #3834 — we should sweep the docs everywhere to fix the issues...

[`Tracer`](/docs/concepts/signals/traces/#tracer).

the `instrumentation.ts` (or `instrumentation.js`) file to include all the SDK

js/node/browser references here. The filename references probably need index.php...
