Editor: Update Google Fonts API endpoint for WordPress 7.1

[i-am-chitti]

Updates the default Google Fonts collection endpoint to the WordPress 7.1 versioned path on s.w.org, refreshing the bundled font collection for the 7.1 release.

This bumps the hard-coded wp-7.0 font URL path to wp-7.1 in the default google-fonts collection registration, and updates the matching preview-URL fixtures in the Font Library REST controller tests. It mirrors the change made for the 7.0 release in #64564.

• src/wp-includes/fonts.php — font_families JSON URL for the google-fonts collection.
• tests/phpunit/tests/fonts/font-library/wpRestFontFamiliesController.php — preview URL fixtures.
• tests/phpunit/tests/fonts/font-library/wpRestFontFacesController.php — preview URL fixture.

Note: the tests pass once the regenerated collection JSON is published to s.w.org/images/fonts/wp-7.1/, which is handled separately per the font collection update procedure. I'm already working on it.
