Add info for Server-rendered HTML > Browser SDK trace propagation to Node docs

[mydea]

We have section on this in the laravel docs: https://docs.sentry.io/platforms/php/guides/laravel/performance/distributed-tracing/

But not really anything similar for e.g. node or other languages.

We should add docs for these for all server languages, probably.
