Display summary text for all the subcommands for top level --help option

[kpritam]

Currently running app --help just prints name of the commands but it would be nice if it also prints Summary or Header information along with the name similar to following git --help command

@kpritam I have tried to implement this in #91.

Could it be a valid solution?

@jgoday Nice to see your PR.
I see you are printing complete help i.e. help for nested options as well.

But if you look at git cli, when you say git --help, it does not print nested options. It only prints top level command names and their description.

To see individual help, one need to run for example, git pull --help command.

@kpritam should be fixed now then.
It looks like this

@jgoday I have not tested it but your last screenshot is what I was looking for. 🎉
Maybe it is good to align command name and its description in single line.

@kpritam If we want to display the subcommand name and the description in one line,
we have to decompose the description helpDoc and get his span text to append it with the name.

It would look like the following image

I actually don't mind the description on another line :)
By the by, I've updated the library to the newest version of ZIO and would like to help get it ready for primetime. Let me know if there's anything I can help with :)

I just updated the branch with the changes from zio-cli / master, updated the git example too (to include subcommands help).
Let me know if it's ok :)

Thanks.
