No code block highlighting for `tsx` or `jsx` language

[AljoschaMeyer]

In the rendered docs, a code block labelled with a language of tsx (or jsx for that matter) does not get any highlighting applied:

/**
```tsx
import { Context } from "@macromania/macromania";
import { P, Em } from "@macromania/macromania-html";

const ctx = new Context();
const someHtml = await ctx.evaluate(
    <P clazz="neat">
        This is a <Em>neat</Em> paragraph.
    </P>
);

// Logs `"<p class="neat">This is a <em>neat</em> paragraph</p>"`.
console.log(someHtml);
```
 *
 * @module
 */

Yields:

Changing the language to ts gives highlighting (though it obviously does not handle the tsx syntax correctly):

(independently, that screenshot is running into #742)
