Plugin for WebdriverIO ("wdio" / wdio.conf.js)?

[JoshuaKGoldberg]

Coming over from eslint/eslint#18005 (comment): it'd be great to have a built-in plugin for WebdriverIO. It's a test framework that has a wdio.conf.js file & is used by ESLint.

I'd be happy to contribute this. I don't personally use wdio but it'd be a good motivator for me to contribute to Knip. 😄

Feel free to work on this! I think it should be quite similar to the Ava, Jest and Mocha plugins.

Looks like the main objectives are the same: getting the entry files right and translate things like framework: "mocha" to @wdio/mocha-framework.

Closing in favor of #483
