refactor: move to single-repo pattern for releases

Switch from dual-repo (stable + dev) to single-repo pattern where both
stable and dev releases are published to the same GitHub repository.

Changes:
- Remove GITHUB_REPO routing logic (was causing releases to wrong repo)
- Hardcode all GitHub URLs to cpfarhood/headlamp-polaris-plugin
- Update dev branch metadata to point to main repo
- Keep prerelease flag in metadata for ArtifactHub differentiation
- Workflow pushes both stable and dev releases to same repo
- ArtifactHub will show dev releases under "Include prereleases" toggle

This follows the standard mono-repo release pattern (like Node.js, K8s)
where users see one package with stable/prerelease versions.
