Changes the Connectors screen URL from a query parameter page to a direct file, following the Settings menu naming convention used by other settings pages (`options-general.php`, `options-writing.php`, etc.).
* Adds `src/wp-admin/options-connectors.php` as a direct admin screen file.
* Adds a static submenu entry in `menu.php` at position 12 (after General).
* Removes `_wp_connectors_add_settings_menu_item()` and its `admin_menu` hook from `connectors.php`.
* Updates the `script_module_data` filter from `connectors-wp-admin` to `options-connectors-wp-admin`.
