deps(if-watch): update if-watch to v3.2.1

[brenodt]

Description

Bumps the if-watch version to 3.2.1, aiming to fix #5628.

Since this if-watch PR, the system-configuration version has been updated, which enables compiling for iOS targets.

Notes & open questions

I'm not sure if I should update the changelogs to include the PR link?
Also, should the main libp2p version be bumped to 0.54.3?

I don't see 0.54.2 in crates, so I wasn't sure, but did it anyway to enable testing locally.

This change made possible compiling for aarch64-apple-ios-sim via cargo lipo and using the resulting static lib without XCode complaining about the deprecated interface.

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 @brenodt!

The version bumps of libp2p, libp2p-mdns and libp2p-quic aren't needed because in all of them the version has already been bumped since the last release.
Also, we usually don't do changelog entries when we update dependencies (correct me if I am wrong @jxs).

Hi @elenaf9 , thanks for the review :)
Let me know if there's anything else I missed here.

Hi, and thanks for your PR! I don't think we even need a version bump right? As even the end user can update by doing cargo upgrade -p if-watch and it will update if-watch to 3.2.1
