Extended manifest shasum not updated with base manifest

Medium Severity

The snap.manifest.json shasum was updated to 4+7ZgHt849j2sZQAwxlkGQ4il80SRXMmDYvb7h0+PrI= in this release, but snap.manifest.dev.json in the same package still has a different shasum (yW/4a7WQ2dCmZHAaX6P2tihFF7azVPkpQ0iJlb/v61A=). Since both manifests reference the same bundle (dist/bundle.js), they should have matching shasums. Using the dev manifest for development would fail bundle verification.
