Update dependency https://github.com/google/go-sev-guest

Greetings,

The https://github.com/google/go-sev-guest dependency repository has been updated to remove an outdated dependency.

Could it be possible to update your dependencies accordingly ?

Thanks !

No file or test is named. Inspect the dependency manifests to find the current go-sev-guest reference, review the dependency repository's update, and run the repository's existing tests; done means the project uses the updated dependency without regressions.
