fix: replace github-release plugin with direct curl API call

The github-release plugin was incorrectly detecting and using the
Gitea API instead of GitHub's API. Replaced with direct curl command
that explicitly calls GitHub API to create releases.

This approach:
- Uses curlimages/curl image for lightweight execution
- Directly calls GitHub API v3 with proper authentication
- Avoids any auto-detection issues from the plugin
- Creates releases with full markdown formatting
