[FEAT] Typescript support

[SalahAdDin]

Is your proposal related to a problem?

We want to write our stories using Typescript:

Describe the solution you’d like

Adding type support for the package or write the package in Typescript itself.

Describe alternatives you’ve considered

Disabling typescript for this component. We are type it as a solution, stories/typings.d.ts:

declare module 'storybook-django/src/react' {
  import { ComponentType } from 'react';

  type PatternProps = {
    template: string;
    context: Record<
      string,
      string | number | boolean | object | null | undefined
    >;
  };
  export const Pattern: ComponentType<PatternProps>;
}
