ci: add ipfs cluster deployment with conditional retention

- add cluster deployment to ipfs-websites.collab.ipfscluster.io
- set cluster-pin-expire-in to 90d only for non-main branches (PRs)
- main branch deployments have no expiration
- increase github artifact retention from 1d to 90d
- comment out storacha credentials (to be configured separately)
