📝 Docs: Document hooks better

[jmm]

The main documentation on hooks portrays things as if the hooks will always be the ones from the bdd interface. It would be helpful to note there that there are different interfaces that may use different names for the equivalent hooks. This is especially bad when combined with bug #2207 which makes the bdd interface hooks actually available if using another interface, but with unexpected behavior.

It's especially worth adding that you can call this.skip() inside a test function or a suite's before-all/setup function to mark the test or suite as pending, as this is the only way I have found to make pending suites/tests in the Exports interface.
