chore: use if-watch-plus instead of if-watch

[RawinSader]

Description

Libp2p relies on a package called if-watch@3.2.0 in 4 different places:

• transport/tcp
• transport/quic
• transport/webrtc
• protocol/mdns

This unmaintained library uses a deprecate iOS interface through one of its own dependencies `system-configurations@0.5.0:

• https://discuss.libp2p.io/t/rust-libp2p-link-error-on-ios-undefined-symbols-kscnetworkinterfacetypeirda/2208
• link error on ios: undefined symbols _kSCNetworkInterfaceTypeIrDA #5140

Seeing that our bindings use this deprecated interface, iOS apps will fail to build for everyone using rust-libp2p.

Notes & open questions

• This PR uses a forked version of if-watch that only updates the system-configurations dependency to the latest version that addresses the deprecated interface
• This PR does not cover tests that should fall under system-configurations

Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• A changelog entry has been made in the appropriate crates

Thanks for the PR! Can you update the workspace Cargo.toml as well? :)

Update me if there is anything else I forgot to do :)

Hi, in the rust-libp2p community call I remarked that it was strange that if-watch was unmaintained, but I have since found mxinden/if-watch#37 (comment), I have also acted upon it and wrote mxinden/if-watch#37 (comment). So I suggest we wait to move the repo and I can then accept a PR there and release a new version.
