Improve error messages for invalid checksum while opening zip files #2405
Description
When uploading debug files, we search through ZIP files to see if there are any debug files in them that we need to upload. However, if the ZIP file is corrupted, the entire upload fails with a very vague error message: error: Invalid checksum.
We should update this error message to be more actionable, by at a minimum including the path to the zip file and instructions for how to fix the problem. We may also wish to treat this case simply as a warning.
