To work around an issue in pytest, run tests from empty temp dir

[oleksandr-pavlyk]

Create empty temporary directory to run "pytest" command from to work-around an issue in pytest accessing files/directories it may not have access to during test collection.

pytest-dev/pytest#11904

This should fixed test_windows step failures.

Creating an empty sub-directory within working directory and running pytest from there as suggested in pytest-dev/pytest#11904 did not work on Windows.

Notice that pytest reports "rootdir" as that empty temporary directory, yet it still attempts to traverse "C:\Documents and Settings" and got PermissionError.

So, giving up, I have pushed a change to use "pytest'<8'" when installing pytest in conda environment.

I would allow default path, since it should also in writable location (how would conda install else work)? So conda environment location is located in writable path. Putting conda env in working folder could result in accidental removal and unexpected CI behavior. Same for other job.

[oleksandr-pavlyk]

Good point, but this newly created folder is writable too. It is created by the workflow at the prior step as a sub-folder of the default path.

LGMT! Just small nit.
