feat: allow debug receive outerHTML

[antoniel]

Summary/Motivation (TLDR;)

This PR adds a new feature to the Jest Preview library that allows developers to pass HTML output generated by other libraries to the debug function. Specifically, this PR replaces the current implementation of the debug function in /src/preview.ts with a new function that accepts an HTML string as a parameter. This makes it possible for developers to use other libraries (such as react-native-to-jest-preview) to generate the HTML output for Jest Preview.

Changes Made

This PR modifies the /src/preview.ts file to add support for passing an HTML string to the debug function. Specifically, the debug function has been replaced with a new function that accepts an outerHTML parameter. If the parameter is not provided, the function falls back to the previous behavior of using document.documentElement.outerHTML.

Here is the specific change that was made:

- export function debug(): void {
+ export function debug(outerHTML = document.documentElement.outerHTML): void {
    if (!fs.existsSync(CACHE_FOLDER)) {
      fs.mkdirSync(CACHE_FOLDER, {
        recursive: true,
      });
    }

    fs.writeFileSync(
      path.join(CACHE_FOLDER, 'index.html'),
-     document.documentElement.outerHTML,
+     outerHTML,
    );
  }
