Provide "plugin:deprecate/recommended"

Hi there, thanks for your work with this!

It would be great to have a recommended setting, like other eslint plugins.

So for the simplest use case, we would do:

{
  "extends": ["plugin:deprecate/recommended"]
}

Instead of:

{
    "plugins": ["deprecate"],
    "rules": {
        "deprecate/function": 2,
        "deprecate/member-expression": 2,
        "deprecate/import": 2
    }
}

The second version is always possible for users that want to customize the rules.
But for most, recommended settings are awesome!

Let me know if you're open to a PR!
