'Last Run' column empty for Viewer role in RBAC UI

[tooptoop4]

In 1.10.9 with RBAC UI, and a user who has the Viewer role, the 'Last Run' column on main dags page is empty. It is present for user with Admin role though.

Seems can_last_dagruns "can last dagruns on Airflow" permission is only Admin, should it be on Op, User, Viewer ?

I have made PR #9133 to fix this
