Make shareable config easier to use

[feross]

It would be great if there's some way to avoid having folks need to install 5-6 packages when they're using eslint-config-standard directly.

See:

• standard/eslint-config-standard-react#56 (comment)
• https://eslint.org/docs/developer-guide/shareable-configs#publishing-a-shareable-config

It doesn't seem possible to make things simpler. The instructions say:

If your shareable config depends on a plugin, you should also specify it as a peerDependency (plugins will be loaded relative to the end user’s project, so the end user is required to install the plugins they need). However, if your shareable config depends on a third-party parser or another shareable config, you can specify these packages as dependencies.

We only depend on plugins in eslint-config-standard and eslint-config-standard-jsx, so these must be peer dependencies. We don't depend on other configs or a custom parser (yet).

That's right. Here's the upstream issue to track:
