feat(rust): add getting started docs for tracing

[lcian]

Adds getting started docs for the tracing integration.
This is our most popular integration, so we want to have a dedicated page to give it even more visibility.
Currently the only docs we have for this are here which means they're hard to find, and they only document the tracing functionality.
