Fix fedora-41 workflow failure by hardening host release asset upload

[Copilot]

The build-images workflow was failing in the fedora-41 matrix job during host asset upload, even though image builds completed successfully. The failure came from a brittle release lookup (gh api .../releases/tags/...) returning 404 in the upload step.

• What changed

  • Updated .github/workflows/build-and-release.yml in Upload host assets (custom Content-Type).
  • Replaced tag-to-release lookup via gh api repos/.../releases/tags/... with gh release view ... --json databaseId.
  • Added short retry logic when resolving RELEASE_ID to tolerate release API consistency delays.
  • Kept existing host upload behavior intact (delete existing asset if present, then upload with EFI-specific content type).

• Behavioral impact

  • Removes the failure mode causing fedora-41 (and other matrix jobs) to fail at publish time.
  • Preserves current release semantics and host EFI content-type handling.
