ci: normalize warewulf provisioner for OpenHPC 4

In OpenHPC 2/3, Provisioner=warewulf means Warewulf v3 and
Provisioner=warewulf4 means Warewulf v4. In OpenHPC 4, warewulf
v3 is gone and Provisioner=warewulf means Warewulf v4.

Normalize Provisioner to "warewulf4" when VERSION_MAJOR is 4
so that all existing warewulf4 conditionals in
support_functions.sh are triggered correctly. The normalization
is placed after the recipeFile path assignment to preserve the
correct on-disk path (warewulf/, not warewulf4/).
