Rename Adapter.get to Adapter.lookup

Per rails-api#1017 (comment)
comment by sandstrom in discussion of the inherited hook

> I'm thinking that it would be better to register adapters manually, without using the hook, i.e.
> have people call ActiveModel::Serializer::Adapter.register directly (perhaps in an initializer).

> Possibly, some inspiration can be taken from how ActiveJob adapters are wired[1].

 The registered adapter name is always a String, but may be looked up as a Symbol or String.
 Helpfully, the Symbol or String is underscored, so that `get(:my_adapter)` and `get("MyAdapter")`
