Emitted @media AtRules are invalid

[sandhose]

@import ... media queries; statements emit invalid AtRule, as the AtRule.params is an array instead of being a string.

This breaks the tailwindcss plugin in some scenarios, like:

@import url('./dark.css') screen and (prefered-color-scheme: dark);
@import url('./light.css') screen and (prefered-color-scheme: light);

Compiling this with both the postcss-import and tailwindcss plugin results to:

TypeError: (intermediate value)(intermediate value)(intermediate value).replace is not a function
