Create a reference list with all potential errors and how to resolve them for troubleshooting (IC/OL-->Self-serve)

# New guidance page for error reference (support flows)

## Context

Currently the "save and resume" feature has generic errors coded in. If we want to be more helpful/specific we can look to elaborate on the error codes to offer additional context:

## Key elements
- Guidance page detailing the common language between end-users > clients > us in error reference codes and what they could mean.
- Target audience is client-use to help trouble shoot between us and their form fillers.
- Similar design to date, done in articles

## What we need to consider

- A bug in our system that stops downloads or provides corrupt files
- The end-user's browser blocking the download
- The end-user's browser hitting it's storage limit (10mb for Chrome, 5mb for Safari)
- A form is tampered with while saved and can no longer be uploaded
- A client has changed the form ID, but is still directing end-users to their new form. The end-user has a saved form file for the wrong form ID but expects they can submit.
