doc: fix multi-process guide
* remove outdated chapter reference to Multi-process support.
* html output converts "--" to "-", this is wrong when explaining the
command arguments, used fixed width quotes for them.

DPDK multi-process support can be used to create a set of peer processes where each process performs the same workload.

This model is equivalent to having multiple threads each running the same main-loop function,
