This behaviour with the empty case probably seems a bit odd, but it is consistent with how clap renders an empty help heading.

### What Move the doc-gen binary code into its own crate, separate from the soroban-cli crate, and have it be dependent on the unmerged pull request to clap-markdown that adds support for grouping cli options: - ConnorGray/clap-markdown#48 ### Why The grouped options experience is a massive improvement. It makes the help documentation easier to scan and understand. It's the way the options are organised on the command line and the help markdown documentation should follow suite. While the pull request adds the feature upstream, the pull request hasn't been accepted yet. The clap-markdown dependency isn't needed for the stellar-cli other than doc-gen, so it is in any case good to get the dependency outside of the soroban-cli crate, so that it isn't downloaded by cargo everytime someone installs the stellar-cli. Moving doc-gen into its own crate is trivial because the soroban-cli is designed to be embedded, and achieves that. Additionally because the doc-gen crate does not need to be published it can reference the unreleased pull request without issue.

What
Add support for grouping options under the help headings in markdown output.
Why
Clap supports custom help headings for options. Options assigned a help heading will appear in the terminal output to be grouped under that help heading. For example:
Today clap-markdown renders all options under a single heading,
Options.With this change clap-markdown groups options under their help headings, reflecting the same experience that clap provides on the command line.
For commands with a large number of options that make use of help headings, this significantly lowers the cognitive load of reading the help when rendered in markdown.
