Running multisite tests results in no tests being executed #1326
Description
I just noticed that running composer test-multisite:plugins results in no tests being executed:
Command output
> test-php-multisite
> wp-env run tests-cli --env-cwd=/var/www/html/wp-content/plugins/performance composer test-multisite:plugins
ℹ Starting 'composer test-multisite:plugins' on the tests-cli container.

Composer could not detect the root package (wordpress/performance) version, defaulting to '1.0.0'. See https://getcomposer.org/root-version

✔ Ran `composer test-multisite:plugins` in 'tests-cli'. (in 11s 11ms)
It appears that tests/multisite.xml never got updated to reflect the changes that were made to phpunit.xml.dist.
