Commands to wp-env have been updated to remove quotes and correctly pass through parameters
PHPUnit (and the version of WP used to run it) has been updated, and the test:php script now calls the composer-provided version of phpunit, not whatever's on the container
The custom RTLCSS build config has been removed, now that wp-scripts provides it
This updates the wp-env & wp-scripts JS packages, along with PHPUnit updates.
