Remove old contributors from OWNERS file

[jotak]

We are refreshing the list of maintainers to keep it aligned with the current state of contributions, removing accounts who haven't contributed in the past year.

Thanks @eranra @KalmanMeth and @ronensc for your contributions! You are of course welcome to come back if you wish :-)

PS: also adding new contributors
