switch to upstream gossipsub (#7057)

We forked `gossipsub` into the lighthouse repo sometime ago so that we could iterate quicker on implementing back pressure and IDONTWANT.
Meanwhile we have pushed all our changes upstream and we are now the main maintainers of `rust-libp2p` this allows us to use upstream `gossipsub` again.
Nonetheless we still use our forked repo to give us freedom to experiment with features before submitting them upstream
