fix(toml)!: Remove support for inheriting badges

We allowed `[badges]` to inherit from `[workspace.package.badges]`

This was a bug:
- This was not specified in the RFC
- We did not document this
- Even if someone were to try to guess to use this, it is inconsistent
  with how inheritance works because this should inherit from
  `workspace.badges` instead of `workspace.package.badges`

While keeping in mind that `[badges]` is effectively deprecated.

In that context, I think its safe to break support for this without a
transition period.

Fixes #13643
