[GitHub models] Rename models root command

[Deborah-Digges]

• Closes https://github.com/github/models/issues/318

Interestingly, it seems like it's not possible to have a multi word usage command for a single command: spf13/cobra#1057

We have a few options:

• I looked at the way other extensions do it and they seem to use hyphenated words, which isn't exactly right. For example, gh-discussions uses the command gh-discussions which looks like this and isn't exactly right because running gh-discussions edit is not a valid command

@Deborah-Digges ➜ /workspaces/gh-models $ gh discussions --help
A CLI for GitHub Discussions
While not complete by any means, this CLI is intended to provide a quick way to
interact with GitHub Discussions from the GH CLI. PRs welcome!

Usage:
  gh-discussions [flags]
  gh-discussions [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  create      Create a discusson from the command line.
  edit        Edit a discusson from the command line.
  help        Help about any command

• The other option could be to change it to just be models, such that the help command looks like this. This feels more correct than the previous option:

@Deborah-Digges ➜ /workspaces/gh-models $ gh models --help
GitHub Models extension

Usage:
  models [command]

Available Commands:
  completion  Generate the autocompletion script for the specified shell
  help        Help about any command
  list        List available models
  run         Run inference with the specified model

Flags:
  -h, --help   help for models

Use "models [command] --help" for more information about a command.

I dont exactly know how, but I think gh-dash was able to make a multi word usage.

╰─\models:garman-patch-1:% gh dash --help
A gh extension that shows a configurable dashboard of pull requests and issues.

Usage:
  gh dash [flags]

Flags:
  -c, --config string   use this configuration file (default is $GH_DASH_CONFIG, or if not set,
                        $XDG_CONFIG_HOME/gh-dash/config.yml)
      --debug           passing this flag will allow writing debug output to debug.log
  -h, --help            help for gh-dash
  -v, --version         version for gh

spf13/cobra#1057 eventually links to kubernetes-sigs/krew#547 which might give extra hints into how to do a multi word usage? Something about needing a "custom usage template," which might be what gh-dash is doing with their cfgFile var?
