Upgrade clap to v4

Close #2846

4.0.0 changelog: 'https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#400---2022-09-28'

I followed the [Migrating steps](https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#migrating) and the only issue I encountered are:
1. The typo problem in previous commit "Fix clap ArgGroup typo"
2. I can't say I am 100% sure every [Subtle changes](https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#breaking-changes) is fine for our use case, but at least after a quick read I didn't notice anything actionable.
