Describe the problem

Currently getContext returns unknown if no explicit type is provided.

Describe the proposed solution

Taking inspiration from svelte-typed-context, getContext can accept an InjectionKey<T>ContextKey<T> and return T:

This will improve type safety and can be done in a backwards compatible way.

The implementation would be just to add a new signature to getContext, setContext and hasContext

export interface ContextKey<T = unknown> { }
export function setContext<T>(key: ContextKey<T>, context: T): void
// getContext ...
// hasContext ...
// check for full implementation here:
// https://github.com/KamenKolev/svelte-typed-context/blob/master/index.ts
// (published npm package does not include `hasContext`, so install only from github)
