No warning/error on referenced but un-existing package

[t-moe]

Lets say I have a workspace with two packages:

• backend
• frontend

And a manually created changeset file with some typos in the packages:

---
backenDD: patch
frontenDD: patch
---

# Initial commit

The knope PrepareRelease step will:

• not consume the changeset
• neither warn nor error out.

Expected behavior:
Error/warn saying that the changeset references an un-existing package.

Note:
We've created a changeset initially with knope document-change, then in response to a PullRequest comment renamed a package in Cargo.toml/knope.toml, but forgot to rename the package in the already created changeset file.

knope --version
knope 0.21.5
