release: 4.0.0-beta.18

[ee7]

Let's create a release for these user-facing commits:

• 8c3e63e create: allow creating of exercise (#845)

The non-using facing commits are:

• 4eeb24f refactor: use QuitSuccess and QuitFailure in quit calls (#852)

• 0d3e407 logger: add withLevel template (#849)

---

I don't like the descripion of --exercise in:

configlet/README.md

Lines 71 to 76 in 8c3e63e

	Options for create:
	--approach <slug> The slug of the approach
	--article <slug> The slug of the article
	--practice-exercise <slug> The slug of the concept exercise
	--concept-exercise <slug> The slug of the practice exercise
	-e, --exercise <slug> Only operate on this exercise

but I don't think it needs to block release. I'd be really helpful if the release notes for this beta could have example usage for create, though.

@ErikSchierboom I've released this. Good to get this out.

Please check the release notes and edit them as you see fit. It would be great if the examples explained --practice-exercise vs --exercise.
