ct_proto() logical_flow actions where added without documentation.
Add documentation for these actions.
Fixes: 889e1fc500a0 ("controller, northd: Add logical flows to use the EVPN
static FDBs.")
Fixes: eba2a1e1ab12 ("Add sctp_abort logical flow action.")
Fixes: 7a72c9812c8c ("action: introduce handle_bfd_msg() action.")
Fixes: 7c3f7f415f1d ("northd, controller: Flood ARP and NA packet on transit
router.")
Fixes: 8e6f9a8355e2 ("northd: Fix HW offload problem related to ct_tuple.")
