fix(tvix/nar-bridge): don't log error on simple 404s r/6612

`nix copy` checks if NARs and NARInfo files are present, before
uploading them. That's not an error, but normal behaviour, so no need to
log with level info for these cases.

We only want to log if the error is not a 404, and log with Warn level.
