Expected a single zip file for markdownZip import

Error message

Expected a single zip file for markdownZip import

What it means

Thrown in the markdownZip import config when the file picker did not yield exactly one file (none or multiple), since markdown zip import accepts a single zip archive only; a caller-input contract violation.
