2851: Upgrade clap to 4.0 r=loiclec a=choznerol

# Pull Request

## Related issue
Fixes #2846 

This PR is draft based on #2847 to avoid conflict. I will rebase and mark as 'Ready for review' after #2847 is merged.

## What does this PR do?
1. Upgrade clap to the latest version or 4.0 (4.0.9 as of today) by following the [migrating instruction](https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#migrating) from [4.0 changelog](https://github.com/clap-rs/clap/blob/master/CHANGELOG.md#migrating)
2. Fix an `ArgGroup` typo that can only be caught after upgrading to 4.0 in 20a715e29ed17c5a76229c98fb31504ada873597

## Notable changes

### The `--help` message

The format, ordering and indentation of `--help` message was changed in 4.0. I recorded the output of `cargo run -- --help` before and after upgrade to 4.0 for reference.
