Fix a typo introduced in #25958.
Speed of Ethernet512 must be 10000 instead of 10.

Why I did it

sonic-cfggen -H -k Mellanox-SN5600-C256S1 --preset t1 > /etc/sonic/config_db.json on SN5600 generates an invalid config that causes ports to have "n/a" operational status.

How I did it

Changed speed of Ethernet512 in device/mellanox/x86_64-nvidia_sn5600-r0/Mellanox-SN5600-C256S1/port_config.ini from 10 to 10000

How to verify it

Under root user on SN5600 switch:

  1. sonic-cfggen -H -k Mellanox-SN5600-C256S1 --preset t1 > /etc/sonic/config_db.json
  2. config reload
  3. show int status should show operational status down or up, depending on devices connected to ports.
