Rename media library modal class

Replace occurrences of .media-library-browser-modal with .media-library-browser-modal-content to keep the modal wrapper class consistent. Updated the source CSS (resources/css/components/media-library.css), the built CSS (resources/dist/components/media-library.css), and the MediaPicker component (src/MediaLibrary/Forms/Components/MediaPicker.php) to use the new class name so styles apply correctly to the modal.
