Update babel-eslint in /packages/generator/app/templates from 9.0.0 to 10.0.0

[dependencies]

Dependencies.io has updated babel-eslint (a npm dependency in /packages/generator/app/templates) from "9.0.0" to "10.0.0".

10.0.0

Small breaking change: add a peerDependency starting from the ESLint version that added a parser feature that we were monkeypatching before (and drop that code). If already using ESLint 5 shouldn't be any different.

• Bugfix for TypeAlias: Support cyclic type declarations (#485) babel/babel-eslint#584

/* flow */
type Node<T> = { head: T; tail: Node<T> }

// or 

type File = {chunks: Array<Chunk>}
type Chunk = {file: File}

• Update to test against ESLint 5, add a peerDependency: Drop old monkeypatching behavior babel/babel-eslint#689
• Drop monkeypatching behavior: Test eslint5, update peerDep babel/babel-eslint#690
