Please document how to run Python tests

[yurivict]

The Build/install page should explain how to run Python exension tests.

Running pytest in any of the directories test/, test/unit_distributed/ fails like this:

[thorstenhater]

Hi @yurivict,

there is a short comment on that, namely here
https://docs.arbor-sim.org/en/stable/contrib/test.html#python-tests
It has proven practical, however, to run the following from the cmake build dir
in the development cycle:

PYTHONPATH=`pwd`/python python3 -munittest discover -v -s ../python

[yurivict]

The above command fails after some tests succeeding:

[thorstenhater]

Does it still fail after traversing to the arbor checkout and using this instead:

PYTHONPATH=<path/to/build> python3 -munittest discover -v -s python

?
Reasoning: Some of our tests build a shared object plugin and it seems the
fixture is misbehaving such that artifact is not found

[thorstenhater]

Coming back to the error log, I'd also suspect something is off with the invocation:
Quoting the log

c++: error: no input files

Possibly skip the relevant tests (those loading plugins) and/or check whether you can build a
plugin like so (after make install; otherwise you'll have to adjust at least PYTHONPATH and PATH)

arbor-build-catalogue dummy [...]/test/unit/dummy/

Output should be similar to this
