Which problem is this pull request solving?

Adds support for .jsx and .tsx entrypoints in edge functions

Describe the solution you've chosen

Deno includes out of the box support for jsx and tsx. However edge bundler doesn't recognise these files, so they can't be used for edge functions at the moment. This PR adds .tsx and .jsx to the list of allowed extensions. It allows things like this:

import React from "https://esm.sh/react@18";
import { renderToReadableStream } from "https://esm.sh/v96/[email protected]/deno/server.js";

export default async function handler(req: Request) {
  const url = new URL(req.url);
  const username = url.searchParams.get("username");

  if (!username) {
    url.searchParams.set("username", "netlify");
    return Response.redirect(url.toString(), 302);
  }

  const controller = new AbortController();
  let didError = false;
  try {
    const stream = await renderToReadableStream(
      <html>
        <title>Hello</title>
        <body>
          <h1>Hello {username}</h1>
        </body>
      </html>,
      {
        signal: controller.signal,
        onError(error: unknown) {
          didError = true;
          console.error(error);
        },
      },
    );

    return new Response(stream, {
      status: didError ? 500 : 200,
      headers: { "Content-Type": "text/html" },
    });
  } catch (error) {
    return new Response(
      "<!doctype html><p>Something went wrong</p>",
      {
        status: 500,
        headers: { "Content-Type": "text/html" },
      },
    );
  }
}

Describe alternatives you've considered

Importing a JSX file into a separate js or ts entrypoint

I thought we'd also need to add .jsx/.tsx here? 🤔

Aaah, it works locally because it's not in a directory. I'll update this
