GenMarkdownTreeCustom doesn't have a way to append a footer

[poy]

GenMarkdownTreeCustom has a way to a header (filePrepender arg), however there is not a first class way to add a footer.

Hi there @poy thanks for opening this issue and contributing!

I believe you are correct, there is no way to add a footer to generated documentation. Can I ask what use case you have for adding a footer to generated documentation? In general, the generated documentation is simply the output of the various "help" messages provided by cobra commands.

We need a way to add something similar to how many websites have their trademark and disclaimers near the bottom of the page. For example, looking at GCS docs, if you look at the bottom of the page you'll see:

Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4.0 License, and code samples are licensed under the Apache 2.0 License. For details, see the Google Developers Site Policies. Java is a registered trademark of Oracle and/or its affiliates.

This is on every docs page for cloud.google.com.

I see - I think that adding a footer makes sense. If you'd (or anyone in the community) would like to open a PR for this, feel free to tag me and I'll review!! 🚀

Re-opening as #1270 had some overlooked breaking changes.

@sonjoonho thanks so much for that PR, if you'd like to take another look and open a new PR, feel free to! Let's avoid any breaking changes in the next pass and I'll keep a closer eye out for it as well

Cheers!
