r/aws_vpc_dhcp_options: fix not found error handling on delete

[jar-b]

Description

The DeleteDhcpOptions API can return a slightly different error code than the associated read operation. This change introduces a new error code constant, preventing the delete operation from failing if the DHCP options have been deleted out-of-band.
