Remove TaskProgressFormats autogenerated file

This file somehow got stuck in the repo although it wasn't actually
used. In fact, it fails to compile at all because
sbt.internal.util.TaskProgress is defined in main, not util-logging. I
noticed this because metals wasn't working well because it was failing
to compile util-logging because of this file. I think the file was
checked in by accident in e28e052b5b.
