Outdated LCM state ID shown in docs

[balazsbme]

Now as a customer asked for ensuring that the LCM state IDs are up to date, I have noticed an inconsistency.

The LCM state with ID 55 has been removed:

one/include/VirtualMachine.h

Line 129 in 47a5d0f

//DISK_SNAPSHOT_REVERT_SUSPENDED = 55,

But still shown in the documentation, both in 7.0 (new website) : https://docs.opennebula.io/7.0/product/operation_references/configuration_references/vm_states/
and in the 6.10: https://docs.opennebula.io/6.10/integration_and_development/references/vm_states.html

Please correct it. I had a look and did not find any other inconsistency in IDs and LCM states.
