Pin pytest to 6.0.2

pytest got upgraded to 6.1.0, and for some reason no longer works with our system. Until we figure out why, pin pytest back to 6.0.2, which does work.

Change seems to me that is working as expected. root cause could be related to:

CMake Warning at /home/jenkins-agent/workspace/ci_linux-aarch64/ws/install/ament_cmake_pytest/share/ament_cmake_pytest/cmake/ament_add_pytest_test.cmake:77 (message):
  The Python module 'pytest' was not found, pytests can not be run (e.g.  on
  Ubuntu/Debian install the package 'python3-pytest')
Call Stack (most recent call first):
  CMakeLists.txt:31 (ament_add_pytest_test)

When I update to 6.1.0 and run pytest locally I get:

  File "/home/ivanpauno/.local/lib/python3.8/site-packages/_pytest/assertion/rewrite.py", line 171, in exec_module
    exec(co, module.__dict__)
  File "/usr/local/lib/python3.8/dist-packages/pytest_rerunfailures.py", line 8, in <module>
    from _pytest.resultlog import ResultLog
ModuleNotFoundError: No module named '_pytest.resultlog'

So it seems that the last pytest update broke pytest-rerunfailures.
There's already an upstream issue: pytest-dev/pytest-rerunfailures#128.

Ah, nice. Thanks for doing the additional research. I'm going to merge this for now, then open up a follow-up PR to unpin.
