Stabilize the current schema

There's...a variety of warts in the current API schema.
In particular I really dislike `.image.image.image`.

But...but...changing it now would in practice be somewhat
difficult, and it's hard to say that just *that* tweak
would be really useful.

Let's just stabilize the existing spec as `v1` and commit
to maintaining it.

We've already added notes to ask callers to use `--format-version 1`
to specify what they want so we can compatibly add new things
in the future.

Speaking of, this also makes `--format-version=1` be the
same thing as `--format-version=0` so that all the versions
are just "1".

Closes: #518

 While bootc does not depend on Kubernetes, it does currently
 also offere a Kubernetes *style* API, especially oriented
 towards the [spec and status and other conventions](https://kubernetes.io/docs/reference/using-api/api-concepts/).
 
 In general, most use cases of driving bootc via API are probably
 most easily done by forking off `bootc upgrade` when desired,
