Fix ios_vlan to correctly identify unmodified config when having long interface names (#40145)

Change the command to get the interface in a vlan "show vlan" => "show vlan brief"
Change the parsing of the return command of the switch.
The return of the ios command is fixed so i cut with fix number of carracter.
Adding looking for the next line to add the forgeted interfaces.
