[via llvm-commits]

https://github.com/bd1976bris created https://github.com/llvm/llvm-project/pull/110922

This adds documentation for --error-display, see: https://github.com/llvm/llvm-project/pull/79648/files.

Note: GitHub won't seem to allow me add the original author @kevinfrei as a reviewer for some reason.
