fix: use named Octokit import

[jlengstorf]

- Summary

Octokit now uses named imports and prints a deprecation notice if you use the default import

[@octokit/rest] `const Octokit = require("@octokit/rest")` is deprecated. Use `const { Octokit } = require("@octokit/rest")` instead

this change swaps out to the named import to remove this deprecation notice

Thanks @jlengstorf, I ran the tests locally and they are passing.
They are failing on your PR since the tests use a GitHub secret which is not available on PRs from forks:

cli/.github/workflows/main.yml

Line 29 in d975672

NETLIFY_AUTH_TOKEN: ${{ secrets.NETLIFY_AUTH_TOKEN }}

We should adjust our GitHub action to consider that

@RaeesBhatti, @jlengstorf I added another commit to sort out the tests.
A bit crude, but we can improve on it.
WDTY?
