Wrong Redirect URIs in .env.example and readme

[mdklause]

The URLs are wrong in .env.example, to get the intended behaviors, the urls needs to be changed to this:

ZITADEL_CALLBACK_URL="http://localhost:3000/api/auth/callback/zitadel" ZITADEL_POST_LOGOUT_URL="http://localhost:3000/api/auth/logout/callback"

These URLs are also partially wrong in the readme.
