Implementation page updates

[Menduist]

Each commit details it's changes, and some could be reverted if deemed inappropriate.

• Update Nim implementation details There was some outdated / missing infos there

• Remove Zig from implementations Everything is missing

• Remove udp & utp transports No one actually implements thoses

• Remove libp2p-dcutr Seems to be the same thing as libp2p-hole-punching?

• Rename libp2p-swarm to libp2p-switch AFAIK swarm is just deprecated terminology for switch

• Change Stream Multiplexing order yamux (default one) -> mplex (common one) -> quic (rare one)

• Remove RendezVous C++ implementation AFAICT it doesn't exist?

The last big one is: Sort implementations by number of implemented protocols

AFAICT, implementations are currently a bit random in their order. The way I see it, we have two ways to sort them which would makes sense: By TIOBE index of the language:

1 "Python"
2 "JVM"
4 "C++"
5 "C#"
7 "JavaScript"
12 "Go"
16 "Swift"
26 "Rust"
42 "Erlang"
70 "Nim"

By number of implemented modules:

     25 "Go"
     20 "Rust"
     20 "JavaScript"
     16 "Nim"
     13 "C++"
     12 "Swift"
      8 "JVM"
      7 "Python"
      5 "Erlang"

(generated by jq 'inputs.libs[].langs[] | select(.status != "Missing").name' data/implementations/* | sort | uniq -c | sort -nr) I think the second one makes more sense, but I'm probably biased here :smile:

The sorting in the JSONs was done by hand, so errors might have slipped through, but I checked a few times and didn't see any
