Incorrect help set emulate docstring

[disconnect3d]

TL;DR the docstring here seems to be copied from vmmap configuration, so it has to be fixed:

pwndbg> help set emulate
Set Unicorn emulation of code near the current instruction.
emulate can be:
off             - read /proc/$qemu-pid/mem to parse kernel page tables to render vmmap
jumps-only      - use QEMU's `monitor info mem` to render vmmap
on              - disable vmmap rendering; useful if rendering is particularly slow

Note that the page-tables method will require the QEMU kernel process to be on the same machine and within the same PID namespace. Running QEMU kernel and GDB in different Docker containers will not work. Consider running both containers with --pid=host (meaning they will see and so be able to interact with all processes on the machine).

Code responsible for it:
