Octokit deprecation warning

[JasonEtco]

Describe the bug

Hey folks 👋 I'm seeing a deprecation warning for @octokit/rest.js when importing @actions/github. This looks to be the offending code (h/t @joshmgross):

toolkit/packages/github/src/github.ts

Line 12 in 432a78c

import Octokit from '@octokit/rest'

And the warning:

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

Looks like perfectly valid warning! cc-ing @gr2m for 👀

Additional context

@actions/github: 2.1.0
@octokit/rest: 16.43.1

Should be fixed now with #332
