test: Show conflicts_with kebab-case failure

[chadoh]

Add a failing test demonstrating that conflicts_with fails when given a kebab-case argument.

Given that multi-word arguments are referred to using kebab-case for their long names and when parsed from the command line, it is reasonable to expect that they can be referred to using kebab case when specified in a conflicts_with argument.

This worked in Clap v3 (or at least v3.1.8, see stellar/soroban-cli#491)

This is covered in the 4.0.0 changelog under

(derive) Leave Arg::id as verbatim casing, requiring updating of string references to other args like in conflicts_with or requires (#3282)

You need to update conflicts_with = "hh-os" to conflicts_with = "hh_os"

Also, in the future I would prefer Discussions for support or Issues for presumed bugs,. leaving PRs for a fix once there is an agreed to problem. This makes makes it much easier to track the various conversations.

Thanks, @epage!

I wanted to make some sort of paper trail (like a PR) to make the problem & solution easier to find for others.

I thought open source etiquette was always to add PRs for (presumed) bugs with failing tests demonstrating the exact behavior in question. Sorry about that; I'll make a Discussion next time.
