@snowpack/plugin-webpack doesn't extract css due to incomplete regex

[greuben]

Svelte component:

<p>Test</p>

<style>
p { color: red; };
</style>

Generates

import './Test.css.proxy.js';

[component code]

css from svelte templates are still inlined in js files because it generates code that proxy-import-resolve.js ignores.

return source.replace(/from\s*['"].*\.(\w+)\.proxy\.js['"]/g, (fullMatch, originalExt) => {

Fix:

return source.replace(/(?:import|from)\s*['"].*\.(\w+)\.proxy\.js['"]/g, (fullMatch, originalExt) => {
