fix(ci): restore go-ipfs publishing to NPM

[lidel]

This PR aims to fix NPM publishing.

It fails due to.. git binary being out of date? https://github.com/ipfs/npm-go-ipfs/runs/2585452310?check_suite_focus=true

npm ERR! Command failed: git commit -m 0.9.0-rc1
npm ERR! git: 'restore' is not a git command. See 'git --help'.

• [x] Switch Node to LTS
  • Ensures package works with LTS + 15 would cause issue described in https://github.com/ipfs/npm-go-ipfs/issues/36
• [x] Fix use of git restore in package.json – github seems to have old git version
