Pass original commit status information

[bahmutov]

When creating JSON block for other operations, also pass original repo information so we can set status back

Right now

const commitMessageInstructions = getInstallJson(
  npm,
  env,
  platform,
  shortNpmVersion, // use as version as branch name on test projects
  commitInfo && commitInfo.sha
)
const jsonBlock = toMarkdownJsonBlock(commitMessageInstructions)

Note that produces block has the commit SHA

[bahmutov]

probably just an object with

{
  status: {
    owner // GitHub organization owner
    repo // GitHub repo
    sha // commit sha to report on
  }
}
