Missing Docs

[drusellers]

Hello Team 👋

I'm working on writing my first Wix installer, and I'm running into some issues with the documentation. Namely, the documentation is missing for https://wixtoolset.org/docs/tools/payloads/

Additionally, I'm not sure what a "Burn Bundle" is as mentioned here - https://wixtoolset.org/docs/tools/burn/
My guess is that a Burn bundle is a branded name for the Bundle, and is a part of the overall naming flavor of Wix, Candle, Light, Burn etc. An overview of these terms and what they mean and how they relate to each other would be much appreciated on this page: https://wixtoolset.org/docs/tools/

If I can learn these items, I'm happy to make pull requests to help document them - but I just don't know what they are yet. :)
