Adding a new workflow should work on our 0-day-bot. We now support 
having multiple workflows so this looks good

nit: Please add a comment for when this is scheduled so we dont have to 
do cron math :)

I think I understand. I think you mean s/GitHub APP/GitHub/ . otherwise 
I dont know what that is. From my understanding you had to request 
special arm-based runners from github

Are DPDK/dpdk and ovsrobot/dpdk whitelisted to use the arm-based runners?

Maybe there was a thread about this in the past that I missed, but where 
and how do you get these arm-based runners from github?
