Following on from https://projects.theforeman.org/issues/25117 which added IdM as a recognised realm_type to the kickstart default kickstart template, IdM should also be added to the other two templates that allow FreeIPA namely kickstart_default_user_data.erb and kickstart_default_finish.erb

Again this means replacing:
<% if host_enc['parameters']['realm'] && @host.realm && @host.realm.realm_type == 'FreeIPA' ->
with:
<% if host_enc['parameters']['realm'] && @host.realm && (@host.realm.realm_type 'FreeIPA' || @host.realm.realm_type 'Red Hat Identity Management') -%>
