fix: handle when FileSystem already exists

[AriaMoradi]

Fixes #1138

We verified this works with fat jars with our own.

Reference: Suwayomi/Suwayomi-Server#462

The implementation looks good, can you add a test where the jar file system already exists and playwright would throw without the fix?

I believe you can do something like ./tools/test-cli-version and in the main test file create jar file system before calling playwright, something like

    URI uri = new URI("jar:file:/home/user/.m2/repository/com/microsoft/playwright/driver-bundle/1.28.0/driver-bundle-1.28.0.jar!/driver/linux");
    FileSystem fs = FileSystems.newFileSystem(uri, Collections.emptyMap());
    assertNotNull(fs);
    try (Playwright playwright = Playwright.create()) {
      Browser browser = playwright.chromium().launch();
      Page page = browser.newPage();
    }

Looks like the Test CLI action ran successfully this time around 🎉

Is this ready to merge?

Yes, it's ready to be merged, you can do that or I can merge later once the tests complete. Thanks for addressing all the comments!
