release: ignore AWS SDK vulnerability for release

The reported AWS S3 vulnerability was inherited from the go-getter
module that Packer uses for downloading files from external sources.

This vulnerability only impacts S3 uploads, therefore Packer is not
vulnerable itself as go-getter only downloads such blobs.

Since the change required to fix this advisory would be to bump the AWS
SDK to v2, this being a major change, is not something to do lightly, so
we opted to ignore this advisory for now so it doesn't block upcoming
releases.
