Check hash of downloaded WRAPS artifact against a hard-coded value

[anthony-swirldslabs]

Build scripts download the WRAPS artifacts for tests. We want to hash the downloaded file and verify it's the one we expect.

Note that we may choose to bake the artifact into the CI runner image and avoid having to download it in the first place.

Also, we probably want to do this after the TSS Ceremony completes, so as not to hash the current artifacts which is somewhat dummy.
