ci: refine release workflow path filters to include changesets (#547)

Improved GitHub workflow path filtering for releases

This PR updates the release workflow to use a more explicit path filtering approach. Instead of using `paths-ignore`, it now uses a combination of include and exclude patterns to better control which files trigger the workflow:

- Includes all files by default
- Excludes website, example-flows, demo, and markdown files
- Re-includes changeset markdown files (except the README)

This approach provides more precise control over which files trigger the release workflow, ensuring changesets are properly processed.
