feat(releaseType): expose at hooks ("major", "minor", ...)

[kazupon]

Sometimes it is useful to pass release type as the release meta information to hooks.

e.g. shipjs.config.js:

  const releaseEmoji = {
    patch: ':sparkles:',
    minor: ':tada:',
    major: ':confetti_ball:',
    // ...
  }
  formatCommitMessage: ({ version, type, }) => 
    `${releaseEmoji[type]}: release(${type}) v${version}`

I've also passed release Type or type as an argument to some hooks as release type.

For consistency, what about using releaseType everywhere? What do you think?

[kazupon]

indeed, that's make sense.
I'll try to fix.
