Comet Lake guide improvement for Intel I225-V Controller.

**Regarding Sections:**

- Device Properties for I225V 2.5 Gbit Controller.:https://dortania.github.io/OpenCore-Install-Guide/config.plist/comet-lake.html#add-2
- Kerel Patch to enable i225V in Catalina to Big Sur 11.3: https://dortania.github.io/OpenCore-Install-Guide/config.plist/comet-lake.html#patch-2

**Suggestion**:
- Remove both Instructions
- Point Users towards [**AppleIGC.kext**](https://github.com/SongXiaoXi/AppleIGC) in the Kernel/Add section instead. The kext enables the Intel I225-V in Catalina and newer without addtional Device Propwerties and the Kernel Patch. I've tested this on my Gigabyte Z490 Vision G Board in macOS 10.15.7 to Somoma.

Greetings.
