Add model_marginaleffects to pkgdown reference list

[moritzkoerber]

Currently, the pkgdown build workflow fails because model_marginaleffects is not listed in the reference index: https://github.com/easystats/modelbased/runs/5433065598?check_suite_focus=true#step:10:66

See also the pkgdown documentation on this.

This PR adds model_marginaleffects to the refences under "Miscellaenous".

Thanks!

Websites builds are still failing, but due to errors in vignettes.

@DominiqueMakowski The vignette build fails here:

Quitting from lines 160-173 (describe_nonlinear.Rmd) 
Error in .get_datagrid_clean_target(x, ...) :

Hm, could be that target is already given as an argument in an underlying function further down the line, e.g. in insight::get_datagrid.data.frame

[IndrajeetPatil]

Possible. Looks like this might be due to some internal restructuring of functions that has happened recently.

Thansk for the notif, will fix it
