Change io/ioutil to io/os packages because io/ioutil package is deprecated from 1.16: Discard => io.Discard NopCloser => io.NopCloser ReadAll => io.ReadAll ReadDir => os.ReadDir ReadFile => os.ReadFile TempDir => os.MkdirTemp TempFile => os.CreateTemp WriteFile => os.WriteFile Details: https://go.dev/doc/go1.16#ioutil Fixes: #3265 Signed-off-by: bin <bin@hyper.sh>
