Describe the bug

I tried to install babel plugin to use jsx inside of .js files in my project.
since I'm extremely familiar and comfortable with the webpack and most of my files are in .js format.

but after installing babel and adding it to my config.mjs file. it gives me the error I've mentioned in the title.

it points to index.ts but I've never changed that file and in fact, whenever I remove babel plugin from my config.mjs file, the issue, goes away.

I wish there could be a built-in support to write jsx in js.

Steps to reproduce

1. npx create-snowpack-app new-dir --template @snowpack/app-template-react-typescript
2. npm install --save-dev @snowpack/plugin-babel
3. npm install --save-dev @babel/preset-react
4. npm install --save-dev @babel/plugin-transform-react-jsx
5. setting up the snowpack.config.mjs

/** @type {import("snowpack").SnowpackUserConfig } */
export default {
  mount: {
    public: { url: '/', static: true },
    src: { url: '/dist' },
  },
  plugins: [
    '@snowpack/plugin-react-refresh',
    '@snowpack/plugin-dotenv',
    ['@snowpack/plugin-babel'],
    [
      '@snowpack/plugin-typescript',
      {
        /* Yarn PnP workaround: see https://www.npmjs.com/package/@snowpack/plugin-typescript */
        ...(process.versions.pnp ? { tsc: 'yarn pnpify tsc' } : {}),
      },
    ],
  ],
  routes: [
    /* Enable an SPA Fallback in development: */
    // {"match": "routes", "src": ".*", "dest": "/index.html"},
  ],
  optimize: {
    /* Example: Bundle your final build: */
    // "bundle": true,
  },
  packageOptions: {
    /* ... */
  },
  devOptions: {
    /* ... */
  },
  buildOptions: {
    /* ... */
  },
};

6. setting up .babelrc config:

{
    "presets": ["@babel/preset-env", "@babel/preset-react"],
    "plugins": ["@babel/plugin-transform-react-jsx"]
}

7. placing .bablerc in the root directory:
