[Minor] Consider using mixin plugin for compat mixins

[slava110]

Hi. When I start minecraft instance, errors are shown in the console

[10:07:03] [main/WARN] [mixin/]: Error loading class: com/simibubi/create/content/trains/display/FlapDisplayRenderer$FlapDisplayRenderOutput (java.lang.ClassNotFoundException: com.simibubi.create.content.trains.display.FlapDisplayRenderer$FlapDisplayRenderOutput)
[10:07:03] [main/WARN] [mixin/]: Error loading class: com/simibubi/create/content/trains/display/FlapDisplaySection (java.lang.ClassNotFoundException: com.simibubi.create.content.trains.display.FlapDisplaySection)
[10:07:03] [main/WARN] [mixin/]: Error loading class: com/simibubi/create/content/trains/display/FlapDisplayRenderer (java.lang.ClassNotFoundException: com.simibubi.create.content.trains.display.FlapDisplayRenderer)
[10:07:03] [main/WARN] [mixin/]: Error loading class: com/hrznstudio/emojiful/ClientEmojiHandler (java.lang.ClassNotFoundException: com.hrznstudio.emojiful.ClientEmojiHandler)

I don't have these mods on my instance. With Mixin Plugin you can filter out mixin classes when specific mods are not present
