Proposed changes

Fix l3ls role documentation about igmp snooping

Current doc

fabric_name: < Fabric_Name >
# Disable IGMP snooping at fabric level.
# If set, it overrides per vlan settings
default_igmp_snooping: < boolean | default -> true >

But according to the code and my tests it is not default_igmp_snooping it is default_igmp_snooping_enabled:

• default_igmp_snooping_enabled (at the root level)
• igmp_snooping_enabled (under l3leaf/default or l3leaf/nodes/xxx) (templates/evpn-fabric-l3leaf-yml.j2)
• igmp_snooping_enabled (under l2leaf/default or l2leaf/nodes/xxx) (templates/evpn-fabric-l2leaf-yml.j2)
• igmp_snooping_enabled (under tenants/vrfs/svis) (templates/tenant_evpn_vxlan/leaf-tenant-igmp-snooping.j2)
• igmp_snooping_enabled (under tenants/l2vlans) (templates/tenant_evpn_vxlan/leaf-tenant-igmp-snooping.j2)
