Add support for TypeScript v6 as a peer dependency

[dennisameling]

When installing @scalar/api-reference-react through pnpm, I got the following peer dependency warning:

 WARN  Issues with peer dependencies found
.
└─┬ @scalar/api-reference-react 0.9.38
  └─┬ @scalar/api-reference 1.57.2

It'd be great if this library could support TypeScript v6 as a peer dependency. I'll file a PR shortly to add that support.
