Builds failing on Windows due to pathing issues

[Skaiir]

Describe the Bug

On Windows specifically, the package cannot be built at all, as multiple modules relating to preact cannot be resolved.

ERROR in ./preact/hooks/dist/hooks.module.js 1:0-37
Module not found: Error: Can't resolve '....' in 'C:\dev\bpmn-io\properties-panel\properties-panel\preact\hooks\dist'
 @ ./src/PropertiesPanel.js 1:0-54 84:30-38 85:2-11
 @ ./test/spec/PropertiesPanel.spec.js 5:0-50 258:21-36
 @ ./test/ sync .spec\.js$ ./spec/PropertiesPanel.spec.js test/spec/PropertiesPanel.spec.js
 @ ./test/testBundle.js 1:17-57

Steps to Reproduce

1. Clone the repo on a Windows machine
2. Execute npm install
3. Execute npm run dev

Expected Behavior

We expect the build to complete without errors.

Environment

• Host: Node v14
• OS: Window 10
• Library version: 0.10.0

Hypothesis: in the rewire step, Windows paths are not properly escaped. Cf.

properties-panel/rollup.config.js

Lines 55 to 74 in 6ceac4f

	function rewirePreactSubpackages() {
	return {
	async buildEnd() {
	await replaceInFile({
	files: './preact/**/*.{js,mjs,js.map}',
	from: [ /(import\s*['"])preact([/'"])/g, /(from\s*['"])preact([/'"])/g, /(require\(['"])preact([/'"])/g ],
	to: function(...args) {
	const importGroup = args[1],
	afterImport = args[2],
	filePath = args.pop();
	const { dir } = parsePath(filePath);
	const pathToPreact = relativePath(dir, './preact');
	return `${importGroup}${pathToPreact}${afterImport}`;
	}
	});
	}
	};
	}

I can't test it on windows right now

Let's also consider adding Windows + Mac as additional OS on CI
