New suggestion for troubleshooting kernel issues

This is a suggestion to the OpenCore Install guide, under Troubleshooting and Kernel issues:
[Stuck on or near IOConsoleUsers: gIOScreenLock.../gIOLockState (3...](https://dortania.github.io/OpenCore-Install-Guide/troubleshooting/extended/kernel-issues.html#stuck-on-or-near-ioconsoleusers-gioscreenlock-giolockstate-3)

I got stuck at this point with my HP Elitedesk 800 G1 and tried all the suggested solutions without luck. I searched the web and found that many guides mentioned that I must not use the VGA port, as that was totally unsupported in MacOS. When I changed to the DisplayPort, the installer finally started. So I suggest that a new point should be something like this:

* You don't use the VGA port on the computer, as that is unsupported in MacOS. Only DisplayPort and HDMI are supported.

Start with the Troubleshooting and Kernel issues section at the linked IOConsoleUsers troubleshooting page and review the existing suggested solutions. Add the VGA-port warning described in the issue, then verify that the guide renders correctly and the new troubleshooting point is clear.
