Arch Loom mixin issues

• Minecraft Development version: 2022.2-1.5.20

• Target platform: Arch Loom 0.12-SNAPSHOT + Mixin 0.8.5

When using Arch Loom in a Forge setup (it's a Forge port of Fabric Loom), the mixin integration of the plugin does not work correctly.

When mixin a class and injecting into a method, the method datatypes autocomplete just fine. Things that don't work are the parameter autocompletion for the target method, the mixin class does not have a quick fix for adding it to the mixin configuration and the mixin configuration has no validation so when adding an invalid mixin class name, it doesn't show an error.

The icons on the left side work fine as well and also navigate you to the right target, just the auto-completion and quick fixes seem to be broken.

Here is a preview of how it looks in Arch Loom compared to Fabric Loom or Forge Gradle.
