feat: simplified pin-params.sh

The pin-params.sh with the fancy "last 3 versions" magic removed,

it
- verifies that you have a single version of the params in /var/tmp/filecoin-proof-parameters
- posts them to cluster via `ipfs-cluster-ctl`
- publishes the new cid to proofs.filecoin.io via `npx dnslink-dnsimple`

you need to install `ipfs-cluster-ctl` and a reasonable verion of node.js >= v10 at a guess.
