Release v5.22.0

copy.Image can now copy non-image OCI artifacts.

Added support for sigstore signatures: they (and related cosign
attachments) can be copied along with images after opt-in in registries.d.
Signatures can be created by copy.Image and enforced via policy.json
(currently with public/private key pairs only).

Now requires Go 1.17.
GPGMe now must be new enough to be visible via pkg-config.

github.com/pkg/errors is no longer used; that might affect
caller-observable error types (in particular, errors.{As,Is}
might need to be used instead of pkg/errors.Cause).
