Fix build with ideaVersion `LATEST-EAP-SNAPSHOT` about mapstruct-idea

[thunderhook]

I thought this would be easy. However, they changed a lot of code. My approach with copying the old classes did not work. They also removed the com.intellij.codeInsight.daemon.impl.quickfix.SideEffectWarningDialog class, see: https://github.com/mapstruct/mapstruct-idea/actions/runs/6916833362/job/18817324564

It is still only in the LATEST-EAP-SNAPSHOT, will be likely in main with 2023.3 though.

I think we should either:

• ignore the failure in the github actions for now
• when 2023.3 is released: maybe disable the WrongUsageOfMappersFactoryInspection (not the most important intention)

I am not sure what happens when we switch to 2023.3 as the main version for development. I think this intention cannot run on older versions then? Or does it just not build with that version? We'll see.

I had a look at it. They didn't remove it. They just changed it. They are now doing:

return new RemoveUnusedVariableFix(variable).asIntention();

I've done PR #162 for this
