ci: download docs-ohpc from EL_10 for non-EL_10 Factory repos

Starting with OpenHPC 4.1, docs-ohpc is only built for EL_10.
When using the Factory repository on other distributions
(e.g. openEuler_24.03), download the noarch RPM from the EL_10
Factory repository and install it locally using dnf download
with --repofrompath.
