🐛 BUG: singleQuote: true does not correctly apply to astro files

[Levelleor]

Describe the Bug

Here's a piece of code from recommended example starter:

---
import astroLogo from "../assets/astro.svg";
import background from "../assets/background.svg";
---

<div id="container">
	<img id="background" src={background.src} alt="" fetchpriority="high" />
	<main>
		<section id="hero">

When running prettier against it the output is:

---
import astroLogo from '../assets/astro.svg';
import background from '../assets/background.svg';
---

<div id="container">
	<img id="background" src={background.src} alt="" fetchpriority="high" />
	<main>
		<section id="hero">

Notice how only the javascript at the top has changed to single quotes and not the rest of the code.

Steps to Reproduce

1. npm create astro@latest using template "A basic, helpful starter project"
2. add .prettierrc file to root
3. add following content to prettier:

{
  "singleQuote": true,
  "bracketSameLine": true,
  "bracketSpacing": true,
  "htmlWhitespaceSensitivity": "ignore"
}

5. The output you can find above.

Have noticed this too, but only when running prettier through CLI. When saving in VSCode the correct formatting is applied.

This creates a discrepancy between the two, and means each are fighting for their own formatting.
