MAINT: pytest doesn't have any more python 3.12 deprecations

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

### Description
<!-- Describe your changes in detail -->
I believe this workaround is not needed any more, pytest doesn't have any more python deprecations. (Arguably neither 3.13)

### Checklist
