updated several packages to update PHPUnit to version 11

- PHPUnit 11 does not allow extensions as it was used in phpunit-injector, so the workaround has been introduced
- PHPUnit 11 no longer supports doc-blocks and uses attributes, so the code has been updated to the new standard
- PHPUnit 11 supports only data providers from the public static method so all providers have been updated
    - this led to rewriting some of the providers and associated methods
- PHPUnit 11 no longer supports abstract mocks so some mocks have to be updated
- setMethods method has been replaced by onlyMethods
