client: Status responses with unknown code are not apistatus.Error

[cthulhu-rider]

any non-zero status sent by the server must be apistatus.Error. But currently https://pkg.go.dev/github.com/nspcc-dev/neofs-sdk-go/client/status#UnrecognizedStatusV2 is not. I find this incorrect

maybe

Steps to Reproduce

func TestUnrecognizedStatus(t *testing.T) {
	require.ErrorIs(t, apistatus.ErrUnrecognizedStatusV2, apistatus.Error)
}

Current Behavior

FAIL

Expected Behavior

PASS

Possible Solution

make it work

Context

Client testing

Regression

no, it is so from the apistatus.Error appearance fc0bd12. Mb @smallhive will remind why

I don't think there is any real reason for that, just an omission.
