It seems that cargo vdev test-vrl does not build from the latest VRL crate. Let me study it.

I execute cargo update to update the vrl crate from latest commit, and the cargo vdev test-vrl do build from the latest change. I am wondering that is it possible to do the same thing in CI stage.

We automated this step but it seems like we haven't been getting update PRs. Nothing to do on your side. We will take care of this PR when the VRL is updated.
