**Describe the bug**
After updating the allure-framework/allure-phpunit:^2.0, No option is available for whether to delete previous results on rerun

**To Reproduce**
Steps to reproduce the behaviour:
1. run the command in your project - composer require allure-framework/allure-phpunit:^2
2. configure the config file
return [
// Path to output directory (default is build/allure-results)
'outputDirectory' => 'var/allure-results',
'deletePreviousResults' => true, //Whether to delete previous results on rerun
'ignoredAnnotations' => [
'codingStandardsIgnoreStart' => 'codingStandardsIgnoreStart',
]
];
