I think we should try to include the actual error text in the feedback report

Information about the context would be good too e.g. to tell the difference between 404 errors in say a. starting a workspace from a repo URL context vs. b. starting a workspace from a snapshot URL

This implementation works, but it is incomplete because the error message text is not included with the feedback. We either have to grab an image, or (better), extract the error message text as a string.

Currently, error handling implementations e.g. in CreateWorkspace.tsx render errors directly to HTML, instead of starting with plaintext first, and then rendering it.

Closing because too stale. Picked up here.
