docs: fix a redirect specified in play-by-play steps

[carloschida]

Since we are running the quick-start locally —at least most will— the actual location of the redirect is http://127.0.0.1:4433/self-service/login/browser and not the one starting with https://playground.projects.oryapis.com/api/kratos/public.

The idea is that you can use the remote playground Kratos for the quickstart or tutorials, without the need for getting it running first. But you are right, in this context that is neither explained nor useful as previous URLs are localhost and you also start Kratos using docker compose.
Tracked that as #1635.
