Print schain name when sent to repair

[kucharskim]

root@c02:~# skale version
SKALE Node CLI version: 2.6.0

We are asked to send schain(s) to repair. I would be operationally useful to see what schain was sent to repair. Current output:

root@c02:~# docker stop skale_admin && \
   skale schains repair wan-red-ain --yes && \
   sleep 5 && \
   skale schains repair portly-passionate-sirius --yes && \
   sleep 10 && \
   docker restart skale_admin
skale_admin
Schain has been set for repair
Schain has been set for repair
skale_admin

Desired output:

Schain <name> has been set for repair
