Fix broken docs links: ResourceSource and TextToSpeechModelSources are type aliases

TypeDoc emits `export type` declarations under `06-api-reference/type-aliases/`,
not `06-api-reference/interfaces/`. The links in useTextToSpeech.md pointed at
the interfaces/ paths, which never get generated for these names, breaking the
Docusaurus build (`onBrokenLinks: 'throw'`).
