Configurable name + tagline of the library in the top bar

[kamilkisiela]

Currently we have:

{
   description: "tagline",
   websiteName: "Hive"
}

and websiteName is linked to ogImage's product parameter and also title's suffix :))

description is misleading a bit as it's not description of a website but the tagline.

What we could have:

{
  logo: {
    title: "Hive",
    tagline: "blah blah blah"
  }
}
