Fix unit test failure caused by numpy update
As always with this file, it fails the PyLint test due to a pre-existing line length which is not fixable. This same PyLint test is then also repeated in the Code Check test.
The Py+CPP checks are not valid for this branch as they attempt to use a toolchain that does not exist in this branch.
Limit the version of numpy that will be accepted
for install to the last one that works.
