Upgrading clap to 4.0.x

[MitchellBerend]

While looking into #133 I ran into a versioning issue between clap and clap_completion. I noticed there was a 4.0 release for clap.

Is it too early to bump the clap version since the 4.0 release was on 2022 09 28? The project passes all tests and compiles and from my own testing everything works as expected. There are a couple of deprecation warnings when running cargo clippy --features clap/deprecated but these are easily fixable.

The main advantage I see are improved help text generation and the auto completion features.

help text 3.2.17

The shell suggestions from the last screenshot also work on 3.x.

No, I don't think so. Upgrading clap sounds like a good idea 👍🏻
tool-sync hasn't been updating dependencies for a while. So it might be a good opportunity to update all the dependencies at once.

But we still might want to upgrade clap separately from other dependencies to make PRs smaller, easier to review and localise all the required changes in a single patch.
