tec: Upgrade to PHPUnit 10

The PHPUnit bridge doesn't fully support PHPUnit 10 officially. I tried
with and without the bridge. I don't get the deprecation notices without
it, while I have them, even without the PHPUnit listener (that I had to
remove).

The rest of the tests doesn't seem to be impacted (I use very few of the
features of the bridge).
