Remove octokit README updates for v7

[joshmgross]

• octokit instance from README examples doesn't work #545

#508 introduced a new octokit variable to make it easier to use examples from GitHub and Octokit docs within actions/github-script.

That change is a breaking change so the README updates shouldn't have been made with v7.

We'll update the README to include this info again when we're ready for v8 - #556

Hello from actions/github-script! (f048dc3)

I dont understand why #508 was a breaking change if it didnt remove any functionality and didnt change existing, it only added to the api surface. Can someone elaborate?

If users are defining a variable named octokit in their scripts (which I suspect some are), then these scripts would fail with the changes introduced by #508

For example:

      - uses: actions/github-script@main
        with:
          script: |
            const octokit = github
            await octokit.rest.issues.createComment({
              owner: context.repo.owner,
              repo: context.repo.repo,
              issue_number: ${{ github.event.issue.number }},
              body: "Hello Again!"
            })

That will fail with the error

Unhandled error: SyntaxError: Identifier 'octokit' has already been declared
