fix(network): set ENR nfd to zero bytes when next fork is unknown (#9009)

Browse Source 
Fixes #8996


  When no next fork is scheduled, the `nfd` field in the ENR was set to the current fork digest via
`.unwrap_or_else(|| ctx.fork_context.current_fork_digest())`.

According to the [spec](1baa05e711/specs/fulu/p2p-interface.md (L636-L637)), `nfd` should be zero-valued bytes when the next fork is unknown.
