Description
Upon inspection of the check_collinearity() function, handling multiple intercepts is currently only supported for mixed models (clm and clmm objects), but not for multinomial logistic regression objects, like car::multinom().
Could you account for the multiple intercepts in these type of models as well?

Research direction
Start by reading check_collinearity() and compare how it handles multiple intercepts for clm and clmm objects. Trace the handling of car::multinom() models, then verify that all intercepts are accounted for and that the existing collinearity checks still behave correctly.
