fix(workflows): standardize release notes generation and add prerelease labels

- Fix release-sdk.yml: Use file-based approach with --notes-file instead of
  complex inline string interpolation to avoid shell parsing errors with
  backticks and special characters

- Fix release.yml: Add --prerelease flag for nightly and preview releases
to properly mark them as pre-releases on GitHub
