Relax pytest requirements in tox

[rominf]

I'm Fedora maintainer of python-pytest-localsever.

Fedora 37 uses python3==3.11.0b3 and pytest==7.1.2, so I had to apply the patch to remove pytest<7 requirement. It looks like all tests pass. Please, consider allowing pytest>=7 for Python 3.11.

Also, Fedora 35 uses pytest==6.2.4, and in tox it's pytest>=6.2.5. I believe that patch version shouldn't matter. Please, consider allowing pytest>=6.2.4 for Python 3.10.

Dropping the pytest <7 requirement is definitely fine with me, and I'm also fine with relaxing the patch level requirement if there isn't a reason for it. Ideally I'd like to hear from @redtoad about whether he had a reason for adding those version constraints.

You give me too much credit here by assuming I had a rational reason for doing so. If I remember correctly, this was done by trial and error.

Fair enough!
