target_package fails if package is provided by another package

[jonjohnsonjr]

This was worked around in chainguard-images/images#1219

But prior to that, we were failing here looking for kubectl:

terraform-provider-apko/internal/provider/tags_data_source.go

Line 117 in 9443d09

resp.Diagnostics.AddError("Unable to find package", fmt.Sprintf("Unable to find package: %s", data.TargetPackage.ValueString()))

Because kubectl is provided by kubernetes-1.28: https://github.com/wolfi-dev/os/blob/cf5b8d25ee5b81041c2d95c3cbabde426415a246/kubernetes-1.28.yaml#L63-L64

We may be able to plumb around from the config data source enough info to fix this.
