Tell the user to try resolve the issue if possible before continuing if there is an error in PreApply

Problem/Motivation

In 📌 If an error occurs during an attended process, delete the stage on behalf of the user Needs review we found that if an error happens in PreApply the user is redirected back to UpdateReady but they have the option to "Continue" or "Cancel Update". But the user should be informed if they could try to resolve this issue if possible before continuing.

Steps to reproduce

Proposed resolution

Update \Drupal\automatic_updates\BatchProcessor::finishCommit() to tell the user to try resolve the issue if possible before continuing if there is an error in PreApply

Remaining tasks
