fix: handle empty releases list in draft cleanup step (#578)

When a new project has no releases yet, `gh api repos/{owner}/{repo}/releases`
returns empty JSON, causing `xargs` to fail with exit code 123:
"unexpected end of JSON input". 
use xargs -r instead of explicit empty check for draft cleanup
