feat: add shared `tsconfig.json`

[natterstefan]

Feature Request

Every new TypeScript project comes the task of creating and maintaining a tsconfig.json. TypeScript configs can also be extended, that is what got me thinking if I should add one to my presets too.

Basic example

"extends": "eslint-config-ns/tsconfig.json"

Motivation

Create a shared tsconfig.json - and probably some presets like tsconfig.jest.jsonortsconfig.cypress.json` - which one can use easily.
