fix(types): NgxKeyValuePair is actually an array

[TPXP]

Proposed changes

Correct the type definition for NgxSharedDict.items(). At runtime, I found out it returns an array of [key, value] objects, just like Object.items(). As documented here https://nginx.org/en/docs/njs/reference.html#dict_items

Types: fixed NgxKeyValuePair definition.

NgxSharedDict.items() returns an array of `[key, value]` pairs, as `Object.entries()`.

Thanks for your feedback, I've reworded the commit and updated the type definition since adding names to array entries doesn't change much indeed (I hoped it would give some hints in IDEs but that does not seem to be the case).
