Better hatch run (and hatch env run)

[kunaltyagi]

Sometimes I forget the scripts provided by the environment. I can perform a hatch env show and check the scripts, but I'd love to have a similar functionality in hatch run --help and hatch env run --help

Usually, my muscle memory already has typed hatch run and then I hit a blank. Getting the list of env:<command> on adding -h would be awesome

Right now you can achieve that with hatch env show but that is an interesting idea. Feel free to open a feature request!
