Critters dont work if the url has a prefix

if you have a build that puts a url in front of the css, this is the `assetsPrefix` option in astro, you will have this difference ```html <link rel="stylesheet" href="http://localhost:4321/_astro/index.Bd8XMnIY.css"> <link rel="stylesheet" href="/_astro/index.Bd8XMnIY.css"> ``` and when you have a prefix with the url or domain dont works well, and don't inline nothing
