Use case: I needed to uninstall tinytex install by Quarto and I wondered how to do that. +

So I ran 
```sh
$ quarto help tools

  Usage:   quarto tools [command:string] [name:string]
  Version: 0.2.188


  Description:

    Manages quarto tools.

    Tools that can be installed include:
      tinytex

  Options:

    -h, --help              - Show this help.
    --log         <level>   - Path to log file
    --log-level   <level>   - Log level (info, warning, error, critical)
    --log-format  <format>  - Log format (plain, json-stream)
    --quiet                 - Suppress console output.

  Commands:

    help  [command]  - Show this help or the help of a sub-command.

  Examples:

    Install TinyTex: quarto tools install tinytex
```

`quarto tools --help` gives the same result. 

There is no mention of available commands. Only an example for install. 
I would expect the `Commands:` part to contain the available commands for `quarto tools` that I can use.

For my need, I tried `quarto tools uninstall tinytex` and it works !

Wouldn't it be interesting to document available commands ? That would help know what is possible. 

From here: https://github.com/quarto-dev/quarto-cli/blob/4c69e93457a49c6530b67550dc46c75d45b44294/src/command/tools/cmd.ts
It seems we can also `update`, and `list` (but the latter is the default action)
