Conflicting docs about default value of (JS) `tracePropagationTargets`

Description

The docs for tracePropagationTargets simultaneously state that the default value is ['localhost', /^\/$/] and ['localhost', /^\//]. I figure it's probably not the first one, because it would seem weird to only attach tracing metadata to requests to / (and that was also added later, in 138df69), but I'm not 100% sure and I can't find the code where it's actually defined.

Suggested Solution

I'm very happy to open a PR if someone can confirm what the default actually is!
