bd25b5f615 fix(yaml): Don't panic on multiple groups
Because we gradually build the `ArgGroup` as we parse the YAML, we don't
use `ArgGroup::new`.  Clap3 introduced an internal `id` in addition to
the public `name` and it appears that this custom initialization code
was not updated.

This shows the problem with publically exposing `impl Default`.
Choices:
- Remove `impl Default`
  - Always valid
  - Requires spreading invariants
  - Callers can't implement code the same way we do
- Add `ArgGroup::name`
  - Can be constructed in an invalid state
  - Centralizes invariants
  - A caller could implement code like the yaml logic

I decided to go with `ArgGroup::name`.

Fixes #2719
