[bgp]: Fix bgp crash after BGP allow list configuration is added (son…

…ic-net#6088)

The issue was a typo introduced in sonic-net#6006. In that change, the BGP allow list
configuration manager was updated to use a method of common ConfigMgr
for restarting peer groups. However, the method name 'restart_peers' was
used instead of the correct 'restart_peer_groups'.

This change updated the managers_allow_list.py to use correct method
'restart_peer_groups' for restarting peer groups.
