Query app version directly by tag

[amcaplan]

WHY are these changes introduced?

Completes https://github.com/Shopify/develop-app-inner-loop/issues/1862

Depends on https://github.com/Shopify/shopify/pull/575881

We are fetching all the versions from app management, and then iterating through them to find the one we want, and then re-fetching that one with full details. But we should just fetch the one we want immediately.

WHAT is this pull request doing?

Uses a new versionByTag field to query for just the version we want (also saves us a request).

How to test your changes?

• List versions of an app you've deployed with p shopify app versions list and choose a different version than is currently deployed. (Best if the app has some extensions.)
• p shopify app release --version YOUR_VERSION_TAG
  • Ensure the version is found correctly
  • Ensure the diff looks correct
