Remove unused dependencies

The @octokit/plugin- references are not actually (directly) used by
@action/github-script and so only serve to confuse about what exact
version of these is included in the action. The actual versions of
these plugins are set by @action/github.

Ignoring newlines, the dist/index.js file is exactly the same without
listing these dependencies in package.json.
