docs: add hub-sync GitHub Action to repo and Spaces docs (#2361)
* docs: update GitHub Actions docs to recommend hub-sync action
Add a new general-purpose GitHub Actions page under Repositories
covering huggingface/hub-sync for Models, Datasets, and Spaces.
Update the Spaces-specific page to lead with hub-sync while keeping
the manual git push approach as a fallback.

* docs: simplify file size section, remove lfs-warning workflow
Keep it to a short note about the LFS requirement rather than
maintaining a separate third-party action reference.
