Update upper-constraints.txt to fix issues with new pytest-cov

Tobiko stopped working after pytest-cov 6.2.0 was released.

With this patch, some versions are updated on upper-constraints.txt,
fixing the compatibility issues.

Zuul jobs template updated to replace openstack-python3-zed-jobs with
openstack-python3-jobs instead, because new versions are not supported
with python3.8.

OSPCIX-912

This patch needs to disable voting from ovs jobs too because of an
unrelated issue:
