Add a "recommended" config to simplify usage

[textbook]

Also make the Rules section of the README a table to track recommended/fixable status.

Meta: When #11 and #12 are merged they should probably be added to the recommended rules as errors; if this PR is merged first I can update the others to use the rule table format and the recommended config.

Hello @textbook - I am not sure how useful an "opinionated" configuration would be at this point. Perhaps when there are so many rules (see eslint) that you have no idea how to get a decent set configured. "Recommended" is also pretty subjective... Perhaps it would be more useful to have a "minimal" rule set (no rules switched on, just keywords) and a "strict" (all rules switched on) ?
Happy to be convinced otherwise 😄

I created the config primarily so you only add to add the plugin once, using extends, rather than needing both plugins and env (which should maybe be codeceptjs/globals, going by other similar packages). My thinking was that "recommended" would turn on the rules that suggest a mistake has been made (interfering with which tests are running can leave you thinking the suite is working when it actually isn't), but leave anything "to taste" out of it.

Ok makes sense. I can see how everyone will go for the recommended configuration.
Personally I would recommend the no-actor-in-scenario rule to encourage using the page-object pattern and thus keeping the test suite maintainable. But perhaps that can be included in a future strict configuration.

I thought about that, but even the docs show mixing actor and page object in their examples, and I definitely found that a useful pattern when writing tests, given the high-level selectors things like I.click give you.

Ok @textbook I can see where you're coming from. The recommended config makes total sense now. While looking at this I came across another idea of providing an all config, the jest plugin does this in a transparent way. But let's get this merged now! 🙂
