#### Stop interpret `*.frag` files as JavaScript files (#17178 by @fisker)

`*.frag` was interpreted as JavaScript files, but `.frag` is also used in GLSL([OpenGL Shading Language](https://en.wikipedia.org/wiki/OpenGL_Shading_Language)). It causes error when Prettier try to format them as JavaScript files.

Since Prettier main, `*.frag` files except `*.start.frag`, `*.end.frag`, `start.frag`, and `end.frag` are no longer treated as JavaScript files.

If you have JavaScript files with `.frag` that do not match the patterns mentioned above, you can config with `overrides`.

```js
export default {
  overrides: {
    files: "**/*.frag",
    options: {
      parser: "babel",
    },
  },
};
```
