feat: add string literal unions typescript generic parsing and test

[yilanboy]

Currently, I'm trying to add Svelte support to this package.

I really appreciate the TypeScript language support, so I can reuse it directly in Svelte.

I noticed that string-literal unions are missing from the generic pattern:

let filter: State<'all' | 'active' | 'done'> = 'all';

So I changed the generic regex pattern slightly:

// from
return '/(?<=\w)(?<match><[A-Z][\w\s,\.\[\]]*>)/';

// to
return '/(?<=\w)(?<match><[A-Z\'"][\w\s,\.\[\]\'"|]*>)/';
