Hello everyone,

I've been updating documentation in kolla-ansible and noticed that while replacing variable content works in https://docs.openstack.org/kolla-ansible it fails to replace the variable with proper content in https://docs.openstack.org/project-deploy-guide/kolla-ansible.

If I understand correctly, it's being substituted with var having proper content in here:
https://opendev.org/openstack/kolla-ansible/src/branch/master/doc/source/conf.py#L150

Later on used in https://opendev.org/openstack/kolla-ansible/src/branch/master/doc/source/conf.py#L162

And now for the example -  |KOLLA_BRANCH_NAME| variable:
Working substitution: 
https://docs.openstack.org/kolla-ansible/latest/user/operating-kolla.html#tools-versioning

Failed to render content:
https://docs.openstack.org/project-deploy-guide/kolla-ansible/latest/quickstart.html#install-kolla-ansible

The var seems to be used the same in both examples, I suspect slightly different configuration on project end of the things.
Can anyone advise where should I start looking?

Best regards,
