* Add a third argument to `WP_Scripts->print_extra_script()`, `$key`, which will be passed to `->get_data()` (no longer passes hardcoded `'data'`) * When `$key` is set to `'data-after'`, the inline script will be printed after the `<script>` tag. If the scripts are being concatenated, all scripts' `'data-after'` data will be printed after the concatenated `<script>` has been rendered. Props hakre, wonderboymusic. Fixes #25277.
