ignore not found file error when watching manifests

[dixudx]

What this PR does / why we need it:
An alternative of #63910.

When using vim to create a new file in manifest folder, a temporary file, with an arbitrary number (like 4913) as its name, will be created to check if a directory is writable and see the resulting ACL.

These temporary files will be deleted later, which should by ignored when watching the manifest folder.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #55928, #59009, #48219
