fix: Avoid sync retry if file/directory was not found

[idsulik]

Description This PR prevents sync retry if the err is related to a missing file/folder. For example - if you use npm to develop, it removes old files and generates new, and if you change files a lot, then the skaffold will try to sync old files several times, but they're deleted.

User facing changes (remove if N/A) Before: Retry sync if a file/folder wasn't found. After: No retry if a file/folder wasn't found.
