feat: add nitro w blobstream

[jcstein]

Overview

• update tutorial to reflect that the integration uses blobstream
• test out local
• test out mocha
• make dx improvements so that we don't have to document janky instructions for mac vs. linux users
  • feat: update sleep and container name to work on both Mac and Linux nitro-testnode#10
• update commits in tutorial, so that the tutorial always works until it needs to be updated. if locked to branch, this is not the case as updates to branch may break tutorial/guide

Checklist

• New and updated code has appropriate documentation
• New and updated code has new and/or updated testing
• Required CI checks are passing
• Visual proof for any user facing features like CLI or documentation updates
• Linked issues closed with keywords
