org.scalafmt.sbt.ScalafmtSbtReporter$ScalafmtSbtError: scalafmt: [v3.7.16] corrupted class path

For example: https://github.com/typelevel/toolkit/actions/runs/6830956374/job/18579714429?pr=122#step:6:25

But this seems to be widespread 🤔

yeah scala steward upgraded this and it broke my CI

The org.scalafmt.interfaces.ScalafmtException: [v3.7.16] corrupted class path: exception is caused by following when running scalafmt cli tool with scalafmt config set to 3.7.16

Updating scalafmt cli tool to the same version 3.7.16 as config file fixed the problem. I assume similar "update" would fix the sbt plugin, which just reports corrupted class path.

The issue seems to be related to the removal/renaming of org.scalafmt.config.Config.
