Fix CI: use github-action build for IPFS hash comments on PRs

- Remove build-test job (build-hash serves as both test and hash poster)
- Remove pull_request trigger (only push events needed)
- Fix command: 'github-action build' instead of 'build github-action build'
  (the wrong command was calling the build subcommand with provider defaulting
  to dappnode, causing ENOTFOUND errors; the correct subcommand uses Pinata)
