Subject: [PATCH] Relax the Python version check for `__class_getitem__` tests

<!-- Provide a general summary of your proposed changes in the Title field above -->

### Description
`__class_getitem__` to support generics was introduced in Python 3.7.
In 3.9 some built-ins were made generic but the functionality
for user-defined classes has been there since 3.7.

### Checklist
<!-- go over following points. check them with an `x` if they do apply, (they turn into clickable checkboxes once the PR is submitted, so no need to do everything at once)

-->
