Export types from create-svelte

[NickantX]

Describe the problem

create-svelte does not export its type definitions, which makes it a bit of a pain to work with in a TypeScript project. It would be helpful for to define types for create-svelte, especially since there is already /types/internal.d.ts.

Describe the proposed solution

Refactor /types/internal.d.ts to also include a declaration for the create function, and reference this file in the package.json for create-svelte.

Alternatives considered

Manually including a type declaration file, and copy-pasting from internal.d.ts
