Values files in package definitions currently expect values files to be in a directory called values. Zarf should not expect users to place their values files in a directory called values, but this directory should be created in a built Zarf package.

For example in a package with the following definition:

kind: ZarfPackageConfig
metadata:
  name: test
values:
  files:
    - values.yaml
components:
  - name: test-component

The user's directory with their zarf.yaml would look like this

.
├── values.yaml
└── zarf.yaml

Then if we decompressed the package, it would look like this:

.
├── checksums.txt
├── values
│   └── values.yaml
└── zarf.yaml

This way the values directory is invisible to the user.
