chore: Enforce array type styles in TypeScript (#5765)

Browse Source 
This change enforces how we type arrays, e.g. choosing between:

* `string[]`
* `Array<string>`

I've gone for the `array-simple` option [1] which enforces that:

* primitive types and type references use `X[]`
* complex types use `Array<X>`

For example, we'd type an array of strings as `string[]`, but an array
of a union type as `Array<SomeUnionType>`.
