More informative error when format-resources isn't found

[Nenuial]

I was hunting an error in one of my extensions today and it took me a very long time to understand what was going wrong. The error message I was getting was ERROR: Source and destination cannot be the same.

This was caused by a missing format ressource I had listed under format-resources. Would it be possible to have a clearer error when this happens?

I just got a similar message

Same message - ERROR: Source and destination cannot be the same.
I published interactively once. Now trying to set up auto-update with linux server and cron.
Everything renders to HTML, then I get this error in the log.

Full details from the log:

@higgi13425 thanks for your feedback. This error message is generic when quarto happens to be in a situation where files need to be copied, but another version of these files already exist at destination.

Following your other issue, I don't think this is related to this old one. Let's not revive old thread - we prefer that new discussion happen in newer thread. Thank you

Done in #10276. Perhaps someday a cleaned up version of this can make it to quarto documentation.
