Fix tests and Docker rebuild due to defunct Schemathesis and pytest dependencies resolution

[juhoinkinen]

Pytest 8.0.0 was released on 2014-01-17. Lately Schemathesis releases have been pinning pytest to <=8, and as Poetry favored pytest over Schemathesis in version resolution, pytest 8 and Schemathesis 3.14.2 (version just before pytest <=8 pinning) are now being installed.

The problem is that tests (and thus Docker rebuild) do not work with this ancient Schemathesis version:

...
RuntimeError: The starlette.testclient module requires the httpx package to be installed.
You can install this with:
    $ pip install httpx 

This is fixed by pinning to pytest 7.*.* in Annif.
