Paraunit 2.2.2: PHPUnit 10.4 support

This is a small patch to smooth the compatibility with the new release of PHPUnit, 10.4. Previous versions would still work fine, but I took the time to fix all the tests (that were broken due to reliance on @internal code such as PHPUnit events) and to add support for the new CLI options regarding the errors baseline.

Paraunit 2.1.0: add --sort=random option

This new minor versions adds a new, small feature to support one small sorting option, the random one. This is useful to mix test execution, if you’re encountering deadlocks and performance bottlenecks due to the concentration of certain tests in some areas of your test suite.
