allure-pytest 2.13.2 will merge parameterized use cases

#### Bug Description
When using @pytest.mark.parametrize() parametrization, the use cases are merged in the generated allure report, and it is not possible to generate an execution result record for each parametrized use case.

#### Steps to reproduce

#### Getting report results
The @pytest.mark.parametrize() parameterization executes four use cases, three of which pass and one of which fails, and sets the failing use case to retry once, and after the execution is complete, the generated allure report can only see the last report record, and the other use case executions are all categorized under " Retries" below

#### Expected Result
It is possible to display execution results for each use case individually, as in allure-pytest 2.13.1.

#### Running environment
- Allure version: 2.13.0
- Test framework: pytest 7.1.0
- Allure adaptor: allure-pytest 2.13.2

まず、pytest 7.1.0 と allure-pytest 2.13.2 を使って @pytest.mark.parametrize() で問題を再現し、その後、生成されたレポートを allure-pytest 2.13.1 のものと比較します。各パラメータ化されたユースケースに、失敗したケースとその再試行を含む固有の実行結果があり、Retries の下にまとめられていなければ完了です。
