chore: update ospo-reusable-workflows org path in CI workflows (#172)

## What

Updated the GitHub Actions reusable workflow references from `github/ospo-reusable-workflows` to `github-community-projects/ospo-reusable-workflows` across auto-labeler, pr-title, and release workflows.

## Why

The ospo-reusable-workflows repository was transferred to the `github-community-projects` organization, so the old `github/` path will stop resolving.

## Notes

- The pinned commit SHA remains unchanged, so the exact same workflow versions are used
- All three workflows (auto-labeler, pr-title, release) were affected
