Profiling docs should mention adding the `bevy/debug` feature

[ickshonpe]

How can Bevy's documentation be improved?

profiling.md says to run your Bevy app with Tracy use --features bevy/trace_tracy --release.

But no debug names are added for Bevy with this setup. It should mention that the bevy/debug feature needs to be enabled for users to be able to track Bevy's own systems.

What about enavling bevy/debug automatically if bevy/trace_tracy is enabled?
