"@types/jest" had a breaking change in 23.3.14

Hey,

So you currently have @types/jest under dependencies:

"dependencies": {
    "@types/jest": "^23.3.10",
    "ts-jest": "~23.10.5"
  },

Version 23.3.13 of @types/jest was compatible all the way down to TypeScript 2.2 I believe.
Version 23.3.14 requires at least TypeScript 2.8, which broke one of our apps build process.

First, do you need @types/jest under dependencies at all? can it be under devDepenedencies instead?

Second, we're currently aiming at ^23.3.10, maybe change it to 23.3.13 just so it won't break apps under TS 2.8?

Thanks.

It should be a dev dep, happy to accept PR :)

I think it was a conscious decision to put it in dependencies, but I'm not sure why.

My idea at the point I put into dependencies was to make it easier when installing the preset. But no problem to put it in dev deps again👍
